== Grundlegende Steuerung ==
'''KRunner''' (auch: "Schnellstartfenster" ; zu Starten per Alt-F2 oder Alt-LEERTASTE) ist ein Programmstarter für die Plasma Umgebung. Seine Grundfunktion besteht im Hochfahren von Programmen aus einer Art von Mini-Kommandozeile, aber erweitert um sogenannte "runners" kann man noch weit mehr diverse Funktionen mit dem KRunner ausüben.


===Krunner syntax===
<div class="mw-translate-fuzzy">
{{Note|1=Distributionsabhängig müssen gegebenfalls "addon" Pakete nachinstalliert werden, um alle hier genannten Funktionen zu erhalten. Mit der Schraubenschlüssel-Klickfläche können addon Pakete aktiviert oder deaktiviert werden, gerade wenn KRunner stark verlangsamt wurde, weil zuviele Pakete dort abgearbeitet werden müssen.}}
</div>


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.
[[Image:KRunner.png||center]]
<span id="Navigating through results"></span>
===Navigating through results===
When search brought more than one result, you can use Tab/Tab+Shift and arrow keys to move forward and backward in result list and use Enter to select a result in addition to using mouse.


==Exploring KRunner's Functions==
== Feature Liste ==
<span id="Using as a calculator"></span>
===Using as a calculator===  


You can use Krunner as a calculator. Just press Alt+F2 and type the expression you want to evaluate such as 32*12= or =32*12. You can put the = sign before or after the expression.
Diese erbärmlich unvollständige Aufzählung unternimmt den Versuch, einige simple Nutzungsmöglichkeiten des '''KRunner''' darzustellen. Bitte das '?' Zeichen anklicken, um weitere Möglichkeiten zu finden.


It is possible to evaluate more sophisticated expressions such as: <code>=sqrt(4) + 32 * sin(60)</code>
=== Programme Starten und Beenden ===
<span id="Using as an application launcher"></span>
===Using as an application launcher===  


This you probably already knew, Krunner can also launch applications.  Start Krunner (Alt+F2) and type the name of the application you want to run.
(builtin plugin: Applications)
<span id="Running BASH commands"></span>
===Running BASH commands===


In addition to applications Krunner also recognizes all binaries throughout your system. You can use this ability to run bash commands such as cp, mv, etc.
<div class="mw-translate-fuzzy">
Sobald man die ersten drei Buchstaben des Programmnamens eingetippt hat, bietet KRunner Namensvervollständigung (herausgesucht aus dem Menü der Anwendungsprogramme) an. Dann Übernahme und Programmstart per ENTER-Taste.
</div>


To do so, start Krunner (Alt+F2) and type the commands just as you would in [[Konsole]]:
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).


cp ~/Documents/myFile ~/myFile  (not a useful example but you get the idea)
Beispiel:
{|class="tablecenter" style="border: 1px solid grey"
| was eingetippt? || was passiert?
|-
| <code> gwe </code> || ''(startet [[Special:myLanguage/Gwenview|Gwenview]])''
|}


===Launching websites===
[[Image:KRunner_app.png||center]]


Enter a URL - <code>http://www.somewhere.com</code> - and the page will pop up in your browser.
<div class="mw-translate-fuzzy">
Ein Programmabbruch läßt sich mit '''KRunner''' bewirken. Dazu <code>kill</code> gefolgt vom Prozessnamen eintippen, dann wird '''KRunner''' SIGTERM (Schließen) und SIGKILL (Abbruch) für das betroffene Programm anbieten. Namensvervollständigung wird nach den ersten drei Buchstaben des Namens eines laufenden Prozesses angeboten.
</div>


===Using web shortcuts===
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.


You can also use web shortcuts with KRunner. Example: <code>gg:some-term</code> will bring up Google search results.
===Direct installation===


In order to use a web shortcut, first make sure it exists and is checked. You can manage them through [[Konqueror]]'s configuration, [[Rekonq]]'s, or try writting <code>Web Shortcuts</code> in KRunner.
(builtin plugin: Software Center)
<span id="KRunner as a unit converter"></span>
===KRunner as a unit converter===


KRunner can help you convert numbers from one unit to another for area, length, mass, speed and volume in KDE SC 4.2 and currency, energy, pressure and  temperature in KDE SC 4.3. For each category, a default unit is set.
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.


''Example'': <code>6 feet in meters</code> will output 1.8288 m.
=== Kommandozeilenbefehle auslösen ===


When you don't give the target unit, conversion is done automatically into default unit of the category.
(builtin plugin: Command Line)


''Example'': <code>10 acres</code> will output 40469 m².
Zusätzlich zu den Programmen aus dem Menü kann '''KRunner''' außerdem Kommandozeilenbefehle ausführen und Binärprogramme starten. Allerdings wird für die Shell Komandos keine Befehlsnamen-Vervollständigung angeboten, man muß also den ganzen Befehl aus dem Gedächtnis kennen.


===Controlling Power Management via PowerDevil addon===
Die Klickfläche mit Schraubenschlüssel-Symbol ermöglicht für diese Art von Befehlsausführung zusätzliche Optionen zu aktivieren. So kann das Ablaufen in der Konsole gewählt werden, etwa um den entstehenden Ausgabetext auch lesen zu können. Oder man kann ein Programm unter einem fremden Benutzer-Konto ausführen, wofür Name und Passwort benötigt wird.


It is possible to control the various PowerDevil options via Krunner:
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''
|}


*'''<code>power profile</code>''' brings up available profiles.
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.
*'''<code>screen brightness</code>''' turns off or dims screen.
*'''<code>screen brightness <percent></code>''' sets the brightness percent of the screen.
*'''<code>suspend</code>''' brings up suspend options.
*'''<code>power governor</code>''' sets the cpu governor.
*'''<code>power scheme</code>''' sets the power scheme.


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''
|}


[[Category:Tutorials]]
===Browse websites===
[[Category:System]]
 
(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]
|}
 
'''KRunner''' intelligently handles units as part of the calculations. Try the following examples to see how.
 
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
|}
 
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.
 
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''' 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.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| 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)
|}
 
===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 <code>spell</code> and can be configured.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> spell linux </code> || 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 <code>#</code> sign.
 
Examples:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> #03b2 </code> || β
|-
|<code> #00b1 </code> || ±
|}
 
===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:
{|class="tablecenter" style="border: 1px solid grey"
| Input || Output
|-
|<code> keyboard </code> || ''opens the Keyboard settings control module''
|-
|<code> fonts </code> || ''opens the fonts settings control module''
|-
|<code> password </code> || ''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:
{|class="tablecenter" style="border: 1px solid grey"
| 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''
|}
 
==Usage==
 
===Open KRunner===
 
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.
 
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>.
 
===Use KRunner===
 
Use <keycap>Tab</keycap>/<keycap>Ctrl+j</keycap> or <keycap>Shift+Tab</keycap>/<keycap>Ctrl+k</keycap> to navigate up and down results. Use <keycap>arrow keys</keycap> to move between options (if any) in a result. Use <keycap>Enter</keycap> (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!

Other languages:

KRunner (auch: "Schnellstartfenster" ; zu Starten per Alt-F2 oder Alt-LEERTASTE) ist ein Programmstarter für die Plasma Umgebung. Seine Grundfunktion besteht im Hochfahren von Programmen aus einer Art von Mini-Kommandozeile, aber erweitert um sogenannte "runners" kann man noch weit mehr diverse Funktionen mit dem KRunner ausüben.

Note

Distributionsabhängig müssen gegebenfalls "addon" Pakete nachinstalliert werden, um alle hier genannten Funktionen zu erhalten. Mit der Schraubenschlüssel-Klickfläche können addon Pakete aktiviert oder deaktiviert werden, gerade wenn KRunner stark verlangsamt wurde, weil zuviele Pakete dort abgearbeitet werden müssen.

Feature Liste

Diese erbärmlich unvollständige Aufzählung unternimmt den Versuch, einige simple Nutzungsmöglichkeiten des KRunner darzustellen. Bitte das '?' Zeichen anklicken, um weitere Möglichkeiten zu finden.

Programme Starten und Beenden

(builtin plugin: Applications)

Sobald man die ersten drei Buchstaben des Programmnamens eingetippt hat, bietet KRunner Namensvervollständigung (herausgesucht aus dem Menü der Anwendungsprogramme) an. Dann Übernahme und Programmstart per ENTER-Taste.

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).

Beispiel:

was eingetippt? was passiert?
gwe (startet Gwenview)

Ein Programmabbruch läßt sich mit KRunner bewirken. Dazu kill gefolgt vom Prozessnamen eintippen, dann wird KRunner SIGTERM (Schließen) und SIGKILL (Abbruch) für das betroffene Programm anbieten. Namensvervollständigung wird nach den ersten drei Buchstaben des Namens eines laufenden Prozesses angeboten.

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.

Kommandozeilenbefehle auslösen

(builtin plugin: Command Line)

Zusätzlich zu den Programmen aus dem Menü kann KRunner außerdem Kommandozeilenbefehle ausführen und Binärprogramme starten. Allerdings wird für die Shell Komandos keine Befehlsnamen-Vervollständigung angeboten, man muß also den ganzen Befehl aus dem Gedächtnis kennen.

Die Klickfläche mit Schraubenschlüssel-Symbol ermöglicht für diese Art von Befehlsausführung zusätzliche Optionen zu aktivieren. So kann das Ablaufen in der Konsole gewählt werden, etwa um den entstehenden Ausgabetext auch lesen zu können. Oder man kann ein Programm unter einem fremden Benutzer-Konto ausführen, wofür Name und Passwort benötigt wird.

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

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!
