'''Krunner''' — это инструмент для поиска и запуска файлов и приложений. Кроме того, он может быть использован для выполнения других операции, например, в качестве калькулятора или преообразователя единиц измерения. ''В большинстве систем Krunner может быть активирован путем нажатия комбинации клавиш <keycap>Alt+F2</keycap>.''
'''KRunner''' (launched with Alt-F2 or Alt-SPACE) is the launcher built into the Plasma desktop. While its basic function is to launch programs from a sort of mini-command-line, its functionality can be extended by "runners" to assist the user to accomplish a lot of tasks.
 
{{Note|1=You may need to install additional '''KRunner''' addons package depending on your distribution to use some of the functionalities listed here. Note that a large number of active addons may slow down the start of KRunner, adjust this by clicking the "settings" icon to the left of the text entry field.}}

==Basic control==
==Features==


===Open KRunner===
This woefully incomplete list attempts to present some basic examples of '''KRunner''' use. Discover more by clicking on the '?' icon in '''KRunner'''.
 
===Start and stop applications===
 
(builtin plugin: Applications)
 
You can launch programs by simply typing the name of the application you want to launch - or even simpler: press the down-arrow key for list of ''most recently used'' programs you typed in beforehand.
 
You may type a single character and KRunner will start finding matches. Matches will be found to applications from your easily customizable applications menu (for that, right-click in menu).
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
| <code> gwe </code> || ''(starts [[Special:myLanguage/Gwenview|Gwenview]])''
|}
 
[[Image:KRunner_app.png||center]]
 
You can use '''KRunner''' to kill applications, too (builtin plugin: Terminate Applications) Type in the keyword <code>kill</code> followed by a process name and '''KRunner''' will provide options to close the application (SIGTERM) or forcibly quit it (SIGKILL). '''KRunner''' will match partial process names to running processes.
 
Note that the keyword <code>kill</code> can be changed in the "Terminate Applications" runner to avoid confusion with the shell command kill which accepts process IDs.
 
===Direct installation===
 
(builtin plugin: Software Center)
 
In case that you look for an application that has not been installed yet, KRunner will suggest a set of applications that match your search. In specific, since KRunner has been integrated with Plasma Software Center, [[Special:myLanguage/Discover | Discover]], will present you a list of applications, enabling you to proceed to direct installation.
 
===Issue (shell) commands===
 
(builtin plugin: Command Line)
 
In addition to applications listed in the applications menu, '''KRunner''' can also be used to run shell commands, including launching binaries. Note that when entering shell commands, '''KRunner''' will not accept partial commands or offer command auto completion.
 
Running a command like this brings up a wrench icon which offers additional options. You can choose to spawn a terminal and run the command there (this can be useful if your command produces text output that you want to read), or choose to run the program as a different user (by providing the username and password of that user).
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> ls ~/Documents </code> || ''lists contents of ~/Documents (preferably in a terminal)''
|-
|<code> cp ~/Documents/myFile ~/myFile </code> || ''copies myFile from ~/Documents to ~/''
|-
|<code> mplayer myMovie.mkv </code> || ''plays myMovie.mkv in mplayer''
|}
 
Incidentally, if the command line is your thing, you may appreciate the built in integration to man pages. Simply type a command name preceded by a <code>#</code> or <code>man:/</code> to open the man page formatted for easy readability in your browser.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> #ls </code> || ''opens the manual for ls in a browser''
|-
|<code> man:/grep </code> || ''opens the manual for grep in a browser''
|}
 
===Browse websites===
 
(builtin plugins: Bookmarks, Locations, Web Search Keywords)
 
You can simply start typing the URL of a website to open it in your default browser. You may even type in the name of a browser bookmark and '''KRunner''' will open it for you. If you have visited the website in the past, '''KRunner''' can fetch you results from your browser's history, too.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> myBookmark </code> || ''opens the bookmark in a browser''
|-
|<code> kde.org </code> || ''opens the [http://www.kde.org KDE homepage] in a browser''
|-
|<code> http://userbase.kde.org/ </code> || ''opens [http://userbase.kde.org/ Userbase] in a browser''
|}
 
'''KRunner''' already knows your Web Shortcuts, found in Plasma System Settings, so you can directly start using them.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> gg:KDE </code> || ''searches Google for KDE''
|-
|<code> wp:krunner </code> || ''searches Wikipedia for krunner''
|}
 
'''KRunner''' also provides options to download files from the web using [[Special:myLanguage/KGet|KGet]] by providing their URL.
 
Additional runners exist for fast searching on Wikipedia, Wikitravel and KDE Techbase.
 
===Open files, folders and devices===
 
(builtin plugin: Locations)
 
'''KRunner''' can also open files and directories on your local machine for you. If you want to browse remote machines, you can do that, too. Notice how '''KRunner''' uses kioslaves for ssh (fish:) and samba (smb:).
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> file:/home/ </code> || ''opens file:///home/ (the Home directory) in [[Special:myLanguage/Dolphin|Dolphin]]''
|-
|<code> file:myMovie.mkv </code> || ''opens /home/myMovie.mkv''
|-
|<code> fish:[email protected] </code> || ''opens fish:/[email protected]/ via fish (file over ssh) protocol''
|-
|<code> smb:myWindowsBox </code> || ''opens smb:/myWindowsBox via Samba''
|}
 
If you don't know the path to a file, simply type the name of the file. If the file is a recently opened document, '''KRunner''' will list it for you. If you have enabled "File Search" provided by [https://community.kde.org/Baloo Baloo] daemon, you can also search your computer for the file by its indexed contents. '''KRunner''' will also open folders you've bookmarked in [[Special:myLanguage/Dolphin|Dolphin]] (in your Places sidebar) if you type their name in. What's more, if you want to access devices on your system (both mounted and unmounted), you can do that, too. '''KRunner''' will even provide device-specific options.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> Home </code> || ''opens the Home directory in [[Special:myLanguage/Dolphin|Dolphin]]''
|-
|<code> myFlashDrive </code> || ''shows options to mount or open the contents of myFlashDrive''
|}
 
===Multitask with sessions, windows, desktops and activities===
 
Several KDE applications allow you to save and load sessions. '''KRunner''' allows you to launch these sessions. You can either type in the name of the application or directly type in the name of the session. Runners exist for opening sessions saved in [[Special:myLanguage/Kate|Kate]], [[Special:myLanguage/Konqueror|Konqueror]], [[Special:myLanguage/Konsole|Konsole]], etc.
 
'''KRunner''' is a multitasker's dream. If you have too many windows open, just type in the title of the window and switch directly to it. You can similarly type in the name of a virtual desktop and switch directly to it. If you roll with activities, switch activities by typing their name in. '''KRunner''' will find a match as soon as you type three characters in.
 
'''KRunner''' will even switch desktop sessions for you. Type in the keyword <code>switch</code> or <code>new session</code> to start a separate X session. You can switch back and forth between sessions by using the <code>switch</code> keyword.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> Desktop 1 </code> || ''switches the virtual desktop to Desktop 1''
|-
|<code> myWorkActivity </code> || ''switches the activity to myWorkActivity''
|-
|<code> switch </code> || ''shows options to switch to an existing session or start a new one''
|-
|<code> new session </code> || ''starts a new session''
|}
 
Several plasma widgets can be launched as windowed applications. You can simply type the name of a widget and '''KRunner''' will launch a window for you.
 
===Talk to people===
 
Type in the name of a contact in your [[Special:myLanguage/KAddressBook|KAddressBook]] to get a list of options to contact them. Typing in an email address into '''KRunner''' will open a [[Special:myLanguage/KMail|KMail]] composer window. You can also search through contacts in your [[Special:myLanguage/Kopete|Kopete]] contact list.
 
The addressbook and kopete runners don't seem to be working in SC 4.8.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> [email protected] </code> || ''compose a mail to the KDE mailing list''
|-
|<code> myContact </code> || ''show options to contact myContact''
|}
 
===Listen to some music===
 
You can control any modern audio player such as [[Special:myLanguage/Amarok|Amarok]] using '''KRunner'''. You can use several keywords (all configurable) to <code>play</code>, <code>pause</code> or skip songs. Typing in the name of an artist, album or song that is in [[Special:myLanguage/Amarok|Amarok]]'s library will let you either play immediately, play next (<code>queue</code>) or play at the end (<code>append</code>) of the current playlist. You can use keywords to <code>increase</code> or <code>decrease</code> the volume of the player, or even to <code>mute</code> or <code>quit</code> it.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> play ''song search'' </code> || ''plays a song immediately''
|-
|<code> pause </code> || ''pauses [[Special:myLanguage/Amarok|Amarok]] or your designated music player''
|-
|<code> next </code> || ''plays next song in playlist''
|}
 
===Be on time===
 
You can get the current date or time by typing in the keywords <code>date</code> or <code>time</code>. Selecting the result will copy it to your clipboard so you can paste it elsewhere. The format of the date and time respects your system settings.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> date </code> || Today's date is ...
|-
|<code> time </code> || The current time is ...
|}
 
[[Image:KRunner_time.png||center]]
 
You can even get the date and time at another location by specifying the time zone or the city listed in the TZ database.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> time UTC </code> || The current time in UTC is ...
|-
|<code> time oslo </code> || The current time in Europe/Oslo is ...
|-
|<code> time kolkata </code> || The current time in Asia/Kolkata is ...
|}
 
There is a runner for interfacing with [[Special:myLanguage/KOrganizer|Korganizer]] and fetching events, but it doesn't seem to be working in SC 4.8.
 
===Calculator===
 
'''KRunner''' features a very versatile calculator that can be called by starting or ending a calculation with an <code>=</code> sign. In addition to basic arithmetic, you can call scientific functions like <code>sqrt()</code>, <code>sin()</code>, <code>log()</code>, etc. A list of the supported functions is [http://qalculate.github.io/manual/qalculate-definitions-functions.html here]. Note that trigonometric functions like <code>sin()</code>, <code>cos()</code>, etc expect the angle in radians. '''KRunner''' understands <code>pi</code> in expressions.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> 32*12 = </code> || 384
|-
|<code> = sqrt(4) + 32*sin(30*pi/180) </code> || 18
|}
 
[[Image:KRunner_calc.png||center]]
 
'''KRunner''' also supports combinatorics functions, like <code>perm()</code> or <code>comb()</code>.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> = perm(10,5) </code> || 30240
|-
|<code> = comb(10,5) </code> || 252
|}
 
'''KRunner''' can also handle symbolic mathematics and perform integration and differentiation on expressions
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> = integrate( -x/y^2, y ) </code> || -x/y
|-
|<code> diff( log(x) ) = </code> || 1/x
|}
 
You can also use '''KRunner''' to solve polynomial functions to find its roots.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> = solve( x^2 + 4*x - 21 = 0 ) </code>|| [3, -7]
|}


There are several ways you can open '''KRunner''':
'''KRunner''' intelligently handles units as part of the calculations. Try the following examples to see how.


* Press its global shortcut (<keycap>Alt + F2</keycap> by default)
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> = 2.5 kg * 10 m/s^2 </code> || 25 N
|-
|<code> 220 V / 10 A = </code> || 22 ohms
|}


* Right click on your [[Special:mylanguage/Plasma|Plasma ]] workspace and choose <menuchoice>Run Command...</menuchoice>
Since '''KRunner''' understands most units, you can use it to convert them very quickly. Note that unit conversions don't require an <code>=</code> sign.


* Run "krunner" command from a console
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> 30 F </code> || -1.11111 degrees C (°C), 273.039 K, ...
|-
|<code> 27.8 km </code> || 1.09449e+06 inches (in), 17.2742 miles (mi), ...
|-
|<code> 5 gallons in liters </code> || 18.9271 liters (l)
|}


===Krunner syntax===
'''KRunner''' knows currencies, too. Conversions between currencies is done by fetching the exchange rate from the [http://www.ecb.int/stats/exchange/eurofxref/html/index.en.html European Central Bank] website.


The '?' icon to the right of the entry field explains the syntax of each of the active''Runners''. Scroll to see all the possible keywords and syntaxes that Runners recognise.
Examples:
<span id="Navigating through results"></span>
{|class="tablecenter" style="border: 1px solid grey"
===Выбор предложенных вариантов===
| Input || Output
|-
|<code> 1 dollar </code> || 0.657002 pounds sterling (GBP), 0.742501 euros (EUR), ...
|-
|<code> 125 euros </code> || 110.606 pounds sterling (GBP), 15,785 yen (JPY), ...
|-
|<code> 30 JPY in RUB </code> || 9.40731 rubles (RUB)
|}


When search brought more than one result, you can use <keycap>Tab</keycap>/<keycap>Tab + Shift</keycap> and <keycap>arrow keys</keycap> to move forward and backward in result list and use <keycap>Enter</keycap> to select a result in addition to using mouse.
===Go places===


==Exploring KRunner's Functions==
If you have bookmarked locations in the '''Marble''' (in OpenStreetMap), '''KRunner''' can open the map directly.
<span id="Using as a calculator"></span>
=== Использование в качестве калькулятора ===


<span class="mw-translate-fuzzy">
===Spell checking and special characters===
Вы можете использовать Krunner в качестве практичного калькулятора. Применять его также просто. Для этого нажмите комбинацию клавиш '''Alt+F2''' и наберите выражение, которое Вы хотите вычислить, например, 32*12= или =32*12 (Вы можете поместить знак '''=''' до или после выражения).
</span>


Также возможно вычисление более сложных выражений, таких как: <code>=sqrt(4) + 32 * sin(60)</code>
'''KRunner''' can tell you whether your spelling is correct and/or suggest corrections. The default keyword to start the spellchecker is <code>spell</code> and can be configured.
<span id="Using as an application launcher"></span>
===Использование для запуска приложений===


<span class="mw-translate-fuzzy">
Examples:
Вероятно Вы уже знаете - Krunner может запускать приложения. Запустите Krunner (Alt+F2) и наберите имя приложения, которое Вы хотите выполнить. Для приложений, находящихся в меню приложений, можно ввести часть его названия или относящиеся к нему ключевые слова. Также можно запускать различные модули настройки, введя их названия или описания.
{|class="tablecenter" style="border: 1px solid grey"
</span>
| Input || Output
<span id="Running BASH commands"></span>
|-
===Выполнение команд BASH===
|<code> spell linux </code> || Suggested words: Linux, lynx, ...
|}


<span class="mw-translate-fuzzy">
'''KRunner''' can also allow you to pick special characters if you can specify the hexadecimal unicode for the character, preceded by a <code>#</code> sign.
Полезной стороной Krunner является то, что он распознает не только  приложения, но и все бинарные файлы внутри вашей системы. Вы можете использовать эту возможность для запуска команд bash, таких как cp, mv и т.д.
</span>


<span class="mw-translate-fuzzy">
Examples:
Чтобы выполнить команду, запустите Krunner (Alt+F2) и наберите команду также, как Вы бы сделали это в [[Konsole]]:
{|class="tablecenter" style="border: 1px solid grey"
</span>
| Input || Output
|-

|<code> #00b1 </code> || ±
|}


<span class="mw-translate-fuzzy">
===Manage your computer===
cp ~/Documents/myFile ~/myFile  (пример бесполезный, приведен для понимания идеи)
</span>


===Открытие веб-сайтов===
You can directly open system settings control modules from '''KRunner'''. Often, if you want to change something, just type associated terms and '''KRunner''' will find the control module with the settings you want.


Введите URL - <code>http://www.somewhere.com</code> - и странице откроется в вашем браузере.
Examples:
{|class="tablecenter" style="border: 1px solid grey"

|<code> password </code> || ''opens the Password & User account control module''
|}


=== Использование веб-сокращений ===
'''KRunner''' can also be used to adjust the screen brightness by using the keywords "screen brightness". You can specify a percentage or just turn the brightness halfway or fully down. Additionally, keywords exist to suspend, logout, shutdown or restart your machine.


<span class="mw-translate-fuzzy">
Examples:
Используйте веб-сокращения: <code>gg:какой-нибудь термин</code> выведет результаты поиска Google.
{|class="tablecenter" style="border: 1px solid grey"
</span>
| Input || Output
|-
|<code> screen brightness 100 </code> || ''increases screen brightness to 100%''
|-
|<code> sleep </code> || ''suspends computer to RAM''
|-
|<code> lock </code> || ''locks the screen''
|-
|<code> restart </code> || ''restarts computer''
|-
|<code> shutdown </code> || ''shutdowns computer''
|}


In order to use a web shortcut, first make sure it exists and is checked. You can manage them through [[Special:myLanguage/Konqueror|Konqueror's]] configuration, [[Special:myLanguage/Rekonq|Rekonq's]], or try writing <code>Web Shortcuts</code> in '''KRunner'''.
==Usage==
<span id="KRunner as a unit converter"></span>
===KRunner в качестве преобразователя единиц измерения===  


KRunner может помочь вам преобразовать значения величин из одной системы единиц в другую, таких как площадь, длина, масса, скорость и объем в KDE SC 4.2. и валюты, энергии, давления и температуры в KDE SC 4.3. Для каждой категории установлена единица измерения по умолчанию.
===Open KRunner===


<span class="mw-translate-fuzzy">
The easiest way to open '''KRunner''' is to trigger its global shortcut (<keycap>Alt+Space</keycap> or <keycap>Alt+F2</keycap>, by default). In some activities (e.g. Desktop), you can simply click on the desktop and start typing. In others (e.g. Search and Launch), '''KRunner''' may be built into the activity itself.
''Пример'': <code>6 футов в метрах</code> выведет <code>1.8288 метров (м)</code>.
</span>


When you don't give the target unit, conversion is done automatically into default unit of the category.  
You can also right-click on your plasma workspace and select <menuchoice>Run Command...</menuchoice> or just simply launch it from the commandline by typing <code>krunner</code>.


''Example'': <code>10 acres</code> will output <code class="output">40469 m²</code>.

===Окна===
Click on the wrench icon to bring up configuration options where you can enable/disable/configure runners that will process your searches. Additional options are available to change the position on the screen where krunner appears. You can even change the style to a task-oriented interface, if you like.


This plug-in allows you to switch to windows or virtual desktops by entering its name. It matches partial window titles, application names (if it can be extracted from the window title) and virtual desktop names.
Clicking on the '?' icon opens a scrollable list that explains the syntax of all the available runners. This is a good way to discover new functionality!
<span id="Tips, Tricks and FAQs"></span>
==Tips, Tricks and FAQs==


==Advanced Usage with Single Runner Mode==
You can use '''KRunner''' in a special "single runner" mode. While in this mode, KRunner will only have one active runner to process your searches. This feature isn't supported by all runners, but quite a few already do. Open the global keyboard shortcuts control module directly from '''KRunner''' and choose the "Run Command Interface" to see what's available. Set a global shortcut for the mode you want and launch '''KRunner''' in that mode. You can have as many modes as you can find shortcuts for. {{Smiley}}


You can use '''KRunner''' in a special mode called "Single Runner Mode", which allows you to restrict your search results to those given by a specific plug-in. For instance, you can restrict search results to the "Windows" runner and browse open windows enjoying the filtering features of the plug-in. Another example would be using the "Devices" runner so that you would be able to browse, mount or unmount devices from within '''KRunner'''.<br />
This [https://sciencekde.wordpress.com/2010/12/07/advanced-calculator-runner/ blog] covers some of the advanced usage of the calculator runner.
An increasing number of plug-ins allow this mode; it is simple to activate it by assigning the corresponding shortcut via the "Global keyboard shortcuts" systemsettings module.

Other languages:

KRunner (launched with Alt-F2 or Alt-SPACE) is the launcher built into the Plasma desktop. While its basic function is to launch programs from a sort of mini-command-line, its functionality can be extended by "runners" to assist the user to accomplish a lot of tasks.

Note

You may need to install additional KRunner addons package depending on your distribution to use some of the functionalities listed here. Note that a large number of active addons may slow down the start of KRunner, adjust this by clicking the "settings" icon to the left of the text entry field.


Features

This woefully incomplete list attempts to present some basic examples of KRunner use. Discover more by clicking on the '?' icon in KRunner.

Start and stop applications

(builtin plugin: Applications)

You can launch programs by simply typing the name of the application you want to launch - or even simpler: press the down-arrow key for list of most recently used programs you typed in beforehand.

You may type a single character and KRunner will start finding matches. Matches will be found to applications from your easily customizable applications menu (for that, right-click in menu).

Examples:

Input Output
gwe (starts Gwenview)

You can use KRunner to kill applications, too (builtin plugin: Terminate Applications) Type in the keyword kill followed by a process name and KRunner will provide options to close the application (SIGTERM) or forcibly quit it (SIGKILL). KRunner will match partial process names to running processes.

Note that the keyword kill can be changed in the "Terminate Applications" runner to avoid confusion with the shell command kill which accepts process IDs.

Direct installation

(builtin plugin: Software Center)

In case that you look for an application that has not been installed yet, KRunner will suggest a set of applications that match your search. In specific, since KRunner has been integrated with Plasma Software Center, Discover, will present you a list of applications, enabling you to proceed to direct installation.

Issue (shell) commands

(builtin plugin: Command Line)

In addition to applications listed in the applications menu, KRunner can also be used to run shell commands, including launching binaries. Note that when entering shell commands, KRunner will not accept partial commands or offer command auto completion.

Running a command like this brings up a wrench icon which offers additional options. You can choose to spawn a terminal and run the command there (this can be useful if your command produces text output that you want to read), or choose to run the program as a different user (by providing the username and password of that user).

Examples:

Input Output
ls ~/Documents lists contents of ~/Documents (preferably in a terminal)
cp ~/Documents/myFile ~/myFile copies myFile from ~/Documents to ~/
mplayer myMovie.mkv plays myMovie.mkv in mplayer

Incidentally, if the command line is your thing, you may appreciate the built in integration to man pages. Simply type a command name preceded by a # or man:/ to open the man page formatted for easy readability in your browser.

Examples:

Input Output
#ls opens the manual for ls in a browser
man:/grep opens the manual for grep in a browser

Browse websites

(builtin plugins: Bookmarks, Locations, Web Search Keywords)

You can simply start typing the URL of a website to open it in your default browser. You may even type in the name of a browser bookmark and KRunner will open it for you. If you have visited the website in the past, KRunner can fetch you results from your browser's history, too.

Examples:

Input Output
myBookmark opens the bookmark in a browser
kde.org opens the KDE homepage in a browser
http://userbase.kde.org/ opens Userbase in a browser

KRunner already knows your Web Shortcuts, found in Plasma System Settings, so you can directly start using them.

Examples:

Input Output
gg:KDE searches Google for KDE
wp:krunner searches Wikipedia for krunner

KRunner also provides options to download files from the web using KGet by providing their URL.

Additional runners exist for fast searching on Wikipedia, Wikitravel and KDE Techbase.

Open files, folders and devices

(builtin plugin: Locations)

KRunner can also open files and directories on your local machine for you. If you want to browse remote machines, you can do that, too. Notice how KRunner uses kioslaves for ssh (fish:) and samba (smb:).

Examples:

Input Output
file:/home/ opens file:///home/ (the Home directory) in Dolphin
file:myMovie.mkv opens /home/myMovie.mkv
fish:[email protected] opens fish:/[email protected]/ via fish (file over ssh) protocol
smb:myWindowsBox opens smb:/myWindowsBox via Samba

If you don't know the path to a file, simply type the name of the file. If the file is a recently opened document, KRunner will list it for you. If you have enabled "File Search" provided by Baloo daemon, you can also search your computer for the file by its indexed contents. KRunner will also open folders you've bookmarked in Dolphin (in your Places sidebar) if you type their name in. What's more, if you want to access devices on your system (both mounted and unmounted), you can do that, too. KRunner will even provide device-specific options.

Examples:

Input Output
Home opens the Home directory in Dolphin
myFlashDrive shows options to mount or open the contents of myFlashDrive

Multitask with sessions, windows, desktops and activities

Several KDE applications allow you to save and load sessions. KRunner allows you to launch these sessions. You can either type in the name of the application or directly type in the name of the session. Runners exist for opening sessions saved in Kate, Konqueror, Konsole, etc.

KRunner is a multitasker's dream. If you have too many windows open, just type in the title of the window and switch directly to it. You can similarly type in the name of a virtual desktop and switch directly to it. If you roll with activities, switch activities by typing their name in. KRunner will find a match as soon as you type three characters in.

KRunner will even switch desktop sessions for you. Type in the keyword switch or new session to start a separate X session. You can switch back and forth between sessions by using the switch keyword.

Examples:

Input Output
Desktop 1 switches the virtual desktop to Desktop 1
myWorkActivity switches the activity to myWorkActivity
switch shows options to switch to an existing session or start a new one
new session starts a new session

Several plasma widgets can be launched as windowed applications. You can simply type the name of a widget and KRunner will launch a window for you.

Talk to people

Type in the name of a contact in your KAddressBook to get a list of options to contact them. Typing in an email address into KRunner will open a KMail composer window. You can also search through contacts in your Kopete contact list.

The addressbook and kopete runners don't seem to be working in SC 4.8.

Examples:

Input Output
[email protected] compose a mail to the KDE mailing list
myContact show options to contact myContact

Listen to some music

You can control any modern audio player such as Amarok using KRunner. You can use several keywords (all configurable) to play, pause or skip songs. Typing in the name of an artist, album or song that is in Amarok's library will let you either play immediately, play next (queue) or play at the end (append) of the current playlist. You can use keywords to increase or decrease the volume of the player, or even to mute or quit it.

Examples:

Input Output
play song search plays a song immediately
pause pauses Amarok or your designated music player
next plays next song in playlist

Be on time

You can get the current date or time by typing in the keywords date or time. Selecting the result will copy it to your clipboard so you can paste it elsewhere. The format of the date and time respects your system settings.

Examples:

Input Output
date Today's date is ...
time The current time is ...

You can even get the date and time at another location by specifying the time zone or the city listed in the TZ database.

Examples:

Input Output
time UTC The current time in UTC is ...
time oslo The current time in Europe/Oslo is ...
time kolkata The current time in Asia/Kolkata is ...

There is a runner for interfacing with Korganizer and fetching events, but it doesn't seem to be working in SC 4.8.

Calculator

KRunner features a very versatile calculator that can be called by starting or ending a calculation with an = sign. In addition to basic arithmetic, you can call scientific functions like sqrt(), sin(), log(), etc. A list of the supported functions is here. Note that trigonometric functions like sin(), cos(), etc expect the angle in radians. KRunner understands pi in expressions.

Examples:

Input Output
32*12 = 384
= sqrt(4) + 32*sin(30*pi/180) 18

KRunner also supports combinatorics functions, like perm() or comb().

Examples:

Input Output
= perm(10,5) 30240
= comb(10,5) 252

KRunner can also handle symbolic mathematics and perform integration and differentiation on expressions

Examples:

Input Output
= integrate( -x/y^2, y ) -x/y
diff( log(x) ) = 1/x

You can also use KRunner to solve polynomial functions to find its roots.

Examples:

Input Output
= solve( x^2 + 4*x - 21 = 0 ) [3, -7]

KRunner intelligently handles units as part of the calculations. Try the following examples to see how.

Examples:

Input Output
= 2.5 kg * 10 m/s^2 25 N
220 V / 10 A = 22 ohms

Since KRunner understands most units, you can use it to convert them very quickly. Note that unit conversions don't require an = sign.

Examples:

Input Output
30 F -1.11111 degrees C (°C), 273.039 K, ...
27.8 km 1.09449e+06 inches (in), 17.2742 miles (mi), ...
5 gallons in liters 18.9271 liters (l)

KRunner knows currencies, too. Conversions between currencies is done by fetching the exchange rate from the European Central Bank website.

Examples:

Input Output
1 dollar 0.657002 pounds sterling (GBP), 0.742501 euros (EUR), ...
125 euros 110.606 pounds sterling (GBP), 15,785 yen (JPY), ...
30 JPY in RUB 9.40731 rubles (RUB)

Go places

If you have bookmarked locations in the Marble (in OpenStreetMap), KRunner can open the map directly.

Spell checking and special characters

KRunner can tell you whether your spelling is correct and/or suggest corrections. The default keyword to start the spellchecker is spell and can be configured.

Examples:

Input Output
spell linux Suggested words: Linux, lynx, ...

KRunner can also allow you to pick special characters if you can specify the hexadecimal unicode for the character, preceded by a # sign.

Examples:

Input Output
#03b2 β
#00b1 ±

Manage your computer

You can directly open system settings control modules from KRunner. Often, if you want to change something, just type associated terms and KRunner will find the control module with the settings you want.

Examples:

Input Output
keyboard opens the Keyboard settings control module
fonts opens the fonts settings control module
password opens the Password & User account control module

KRunner can also be used to adjust the screen brightness by using the keywords "screen brightness". You can specify a percentage or just turn the brightness halfway or fully down. Additionally, keywords exist to suspend, logout, shutdown or restart your machine.

Examples:

Input Output
screen brightness 100 increases screen brightness to 100%
sleep suspends computer to RAM
lock locks the screen
restart restarts computer
shutdown shutdowns computer

Usage

Open KRunner

The easiest way to open KRunner is to trigger its global shortcut (Alt+Space or Alt+F2, by default). In some activities (e.g. Desktop), you can simply click on the desktop and start typing. In others (e.g. Search and Launch), KRunner may be built into the activity itself.

You can also right-click on your plasma workspace and select Run Command... or just simply launch it from the commandline by typing krunner.

Use KRunner

Use Tab/Ctrl+j or Shift+Tab/Ctrl+k to navigate up and down results. Use arrow keys to move between options (if any) in a result. Use Enter (or left click) to select a result.

Discover KRunner

Click on the wrench icon to bring up configuration options where you can enable/disable/configure runners that will process your searches. Additional options are available to change the position on the screen where krunner appears. You can even change the style to a task-oriented interface, if you like.

Clicking on the '?' icon opens a scrollable list that explains the syntax of all the available runners. This is a good way to discover new functionality!

Tips, Tricks and FAQs

You can use KRunner in a special "single runner" mode. While in this mode, KRunner will only have one active runner to process your searches. This feature isn't supported by all runners, but quite a few already do. Open the global keyboard shortcuts control module directly from KRunner and choose the "Run Command Interface" to see what's available. Set a global shortcut for the mode you want and launch KRunner in that mode. You can have as many modes as you can find shortcuts for.

This blog covers some of the advanced usage of the calculator runner.
