'''KRunner''' ist ein Werkzeug zum Suchen und Starten von Dateien und Programmen. Es kann auch für allgemeinere Aufgaben wie Rechnen oder Einheitenumwandlungen verwendet werden. ''Auf den meisten Systemen wird KRunner durch die Tastenkombination <keycap>Alt + F2</keycap> aktiviert.''
+
'''KRunner''' 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.

==Features==
  
===KRunner aufrufen===
+
This woefully incomplete list attempts to present some basic examples of KRunner use. Discover more by clicking on the '?' icon in KRunner!
  
Es gibt verschiedene Wege, um '''KRunner''' aufzurufen:
+
===Start and stop applications===
  
* Die globale Tastenkombination drücken (standardmäßig <keycap>Alt + F2</keycap>)
+
You can launch programs by simply typing the name of the application you want to launch. You need to type at least three characters to start finding matches. Matches will be found to applications in your applications menu.
  
* Rechtsklick auf dem [[Special:mylanguage/Plasma|Plasma-Desktop]] und dann die Option <menuchoice>Befehl ausführen …</menuchoice>
+
Examples:
 +
{|class="tablecenter" style="border: 1px solid grey"
 +
| Input || Output
 +
|-
 +
| <code> gwe </code> || ''(starts [[Special:myLanguage/Gwenview|Gwenview]])''
 +
|}
  
* Den Befehl „krunner“ von einer Konsole ausführen
+
You can use KRunner to kill applications, too. 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 (at least three characters) to running processes.
  
=== KRunner-Syntax ===
+
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.
  
Das '?'-Symbol rechts neben dem Eingabefeld erklärt die Syntax aller aktiven Runner-Module. Blättern Sie durch die Hilfe, um alle möglichen Schlüsselwörter zu sehen, die die Runner verstehen.
+
===Issue (shell) commands===
<span id="Navigating through results"></span>
 
=== Navigieren durch die Ergebnisse ===
 
  
Wenn eine Suche mehr als ein Ergebnis liefert, können Sie sich mit <keykap>Tab</keykap> bzw. <keykap>Umschalt+Tab</keykap> und den <keykap>Pfeiltasten</keykap> vorwärts und rückwärts durch die Ergebnisliste bewegen und die <keykap>Eingabetaste</keykap> oder die Maus verwenden, um ein Ergebnis auszuwählen.
+
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.
  
== Die Funktionen von KRunner ==
+
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).
<span id="Using as a calculator"></span>
 
=== Verwendung als Taschenrechner ===
 
  
Sie können '''KRunner''' als Taschenrechner verwenden. Drücken Sie einfach <keykap>Alt+F2</keykap> und geben Sie den Ausdruck ein, den Sie auswerten möchten, wie z.B. 32*12= oder =32*12. Sie können das =-Zeichen vor oder nach dem Ausdruck eingeben.
+
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''
 +
|}
  
Es ist auch möglich, kompliziertere Ausdrücke zu berechnen, wie <code>=sqrt(4) + 32 * sin(60)</code>
+
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> to open the man page formatted for easy readability in your browser.
  
Since SC 4.5, additional features have been added to the calculator runner, such as equation solving, support for expressions containing units, and more. For a brief overview of these features and an example of the usage, you might be interested in the following [http://sciencekde.wordpress.com/2010/12/07/advanced-calculator-runner/ blog post]. Additionally, a list of the supported functions is provided [http://qalculate.sourceforge.net/gtk-manual/apa.html here].
+
Examples:
<span id="Using as an application launcher"></span>
+
{|class="tablecenter" style="border: 1px solid grey"
=== Verwendung als Anwendungsstarter ===
+
| Input || Output
 +
|-
 +
|<code> #ls </code> || ''opens the manual for ls in a browser''
 +
|}
  
Sie werden vermutlich schon wissen, dass '''KRunner''' auch Anwendungen starten kann. Starten Sie KRunner (<keykap>Alt+F2</keykap>) und geben Sie den Namen der Anwendung an, die Sie starten möchten.
+
===Browse websites===
Um Programme aus dem Menü zu starten, können Sie auch ein Teil des Programmnamens oder einen Teil der Schlüsselwörter der Beschreibung eingeben. Sie können auch den Namen oder die Beschreibung eines bestimmten Kontrollelements nutzen um es zu starten.
 
<span id="Running BASH commands"></span>
 
=== Bash-Befehle ausführen ===  
 
  
Neben den Anwendungen erkennt '''KRunner''' auch alle ausführbaren Programme auf Ihrem System. Sie Können damit Bash-Befehle, wie cp, mv, usw. ausführen.
+
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 bookmark from [[Special:myLanguage/Konqueror|Konqueror]] 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.
  
Dazu starten Sie '''KRunner''' (<keykap>Alt+F2</keykap>) und geben die Befehle ein, wie Sie es in [[Special:myLanguage/Konsole|Konsole]] tu würden.
+
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://www.userbase.kde.org/ Userbase] in a browser'
 +
|}
  
<code>cp ~/Dokumente/meineDatei ~/meineDatei</code>  (ein nicht sehr nützliches Beispiel, aber Sie verstehen, was ich meine)
+
KRunner already knows your web shortcuts in [[Special:myLanguage/Konqueror|Konqueror]], so you can directly start using them.
  
=== Webseiten öffnen ===
+
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''
 +
|}
  
Geben Sie eine URL ein - <code>http://www.somewhere.com</code> - und die Seite wird sich in Ihrem Browser öffnen.
+
KRunner also provides options to download files from the web using [[Special:myLanguage/KGet|KGet]] by providing their URL.
  
=== Webkürzel verwenden ===
+
Additional runners exist for fast searching on Wikipedia, Wikitravel and KDE Techbase.
  
Sie können auch Webkürzel mit '''KRunner''' verwenden, zum Beispiel: <code>gg:ein-Begriff</code> öffnet die Google-Suchergebnisse.
+
===Open files, folders and devices===
  
Um ein Webkürzel zu verwenden, stellen Sie zuerst sicher, dass es existiert und aktiviert ist. Sie können Webkürzel in der Konfiguration von [[Special:myLanguage/Konqueror|Konqueror]] oder [[Special:myLanguage/Rekonq|Rekonq]] verwalten, oder durch die Eingabe von <code>Webkürzel</code> in '''KRunner'''.
+
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:).
<span id="KRunner as a unit converter"></span>
 
=== KRunner als Einheitenumrechner ===
 
  
KRunner kann Werte von einer Einheit in eine andere umwandeln für Flächen-, Längen-, Massen-, Geschwindigkeits- und Volumenmaße in KDE SC 4.2 sowie Energie, Druck und Temperatur in KDE SC 4.3. Für jede Kategorie gibt es eine Stardardeinheit.
+
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].com </code> || ''opens fish:/[email protected].com/ via fish (file over ssh) protocol''
 +
|-
 +
|<code> smb:myWindowsBox </code> || ''opens smb:/myWindowsBox via Samba''
 +
|}
  
''Beispiel'': <code>6 Fuß in Meter</code> ergibt <code class="output">1,8288 m</code> (Meter). Einheiten in Langform müssen mit Großbuchstaben am Anfang geschrieben werden.
+
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 the [[Special:myLanguage/Nepomuk|Nepomuk]] subsystem installed, 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.
  
Wenn Sie keine Zieleinheit angeben, erfolgt die Umwandlung automatisch in die Standardeinheit der Kategorie.
+
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''
 +
|}
  
''Beispiel'': <code>10 Acre</code> ergibt <code class="output">40468,6 Quadratmeter (m²)</code>.
+
===Multitask with sessions, windows, desktops and activities===
<span id="Controlling Power Management via PowerDevil addon"></span>
 
=== Energieverwaltung mit der PowerDevil-Erweiterung ===  
 
  
Man kann die verschiedenen PowerDevil-Optionen mit KRunner steuern:
+
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.
  
*'''<code>Energieprofil</code>''' zeigt die verfügbaren Energieprofile.
+
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.
*'''<code>Bildschirm-Helligkeit</code>''' schaltet den Bildschirm aus oder verdunkelt ihn.
 
*'''<code>Bildschirm-Helligkeit <Prozent></code>''' setzt die Bildschirm-Helligkeit auf Prozent
 
*'''<code>ruhezustand</code>''' zeigt die Ruhezustand-Optionen.
 
*'''<code>Energie-Überwachung</code>''' setzt die CPU-Überwachung.
 
*'''<code>Energiesparsparschema</code>''' setzt das Energiesparschema.
 
  
=== Fenster ===
+
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.
  
Dieser Runner ermöglicht es, zu Fenstern oder virtuellen Arbeitsflächen zu wechseln durch Eingabe des Namens. Er funktioniert mit Teilen von Fenstertiteln, Anwendungsnamen (wenn er im Fenstertitel steht) und Namen von virtuellen Arbeitsflächen.
+
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''
 +
|}
  
== Erweiterte Verwendung mit Single Runner Modus ==
+
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.
  
Sie können KRunner in einem speziellen Modus namens "Single Runner Mode" verwenden, dass Ihnen erlaubt, Suchergebnisse auf bestimmte Erweiterungen zu beschränken. Zum Beispiel können Sie die Suchergebnisse auf den "Fenster" Runner  beschränken und offene Fenster durchsuchen. Ein weiteres Beispiel dürfte die Verwendung des "Geräte" Runners sein, dass Sie in der Lage sein dürften, Geräte zu durchsuchen, einzuhängen oder auszuhängen innerhalb von KRunner.<br />
+
===Talk to people===
Immer mehr Erweiterungen unterstützen diesen Modus; es ist einfach diesen Modus zu aktivieren, indem Sie eine Tastenkombination mittels "Globale Tastaturkombinationen" des Systemeinstellungsmodule festlegen. 
 
  
 +
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.
  
[[Category:Leitfäden/de]]
+
The addressbook and kopete runners don't seem to be working in SC 4.8.
[[Category:System/de]]
+
 
 +
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 ...
 +
|}
 +
 
 +
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.sourceforge.net/gtk-manual/apa.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
 +
|}
 +
 
 +
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>|| [7, -3]
 +
|}
 +
 
 +
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''
 +
|}
 +
 
 +
==Usage==
 +
 
 +
===Open KRunner===
 +
 
 +
The easiest way to open KRunner is to trigger its global shortcut (<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> or <keycap>Shift+Tab</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 waveform icon will open the System Monitor.
 +
 
 +
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. :)
 +

KRunner 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.

KRunner.png

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

You can launch programs by simply typing the name of the application you want to launch. You need to type at least three characters to start finding matches. Matches will be found to applications in your applications menu.

Examples:

Input Output
gwe (starts Gwenview)

You can use KRunner to kill applications, too. 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 (at least three characters) 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.

Issue (shell) commands

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 # to open the man page formatted for easy readability in your browser.

Examples:

Input Output
#ls opens the manual for ls in a browser

Browse websites

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 bookmark from Konqueror 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 in Konqueror, 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

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 the Nepomuk subsystem installed, 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

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 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 ) [7, -3]

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

Usage

Open KRunner

The easiest way to open KRunner is to trigger its global shortcut (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 or Shift+Tab 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 waveform icon will open the System Monitor.

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. :)
