    This woefully incomplete list attempts to present some basic examples of '''KRunner''' use. Discover more by clicking on the '?' icon in '''KRunner'''.
    Diese erbärmlich unvollständige Aufzählung unternimmt den Versuch, einige simple Nutzungsmöglichkeiten des '''KRunner''' darzustellen. Bitte das '?' Zeichen anklicken, um weitere Möglichkeiten zu finden.


    ===Start and stop applications===
    === Programme Starten und Beenden ===


    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.
    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.  


    Examples:
    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:
    {|class="tablecenter" style="border: 1px solid grey"
    {|class="tablecenter" style="border: 1px solid grey"
    | Input || Output
    | was eingetippt? || was passiert?
    |-
    |-
    | <code> gwe </code> || ''(starts [[Special:myLanguage/Gwenview|Gwenview]])''
    | <code> gwe </code> || ''(startet [[Special:myLanguage/Gwenview|Gwenview]])''
    |}
    |}


    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.

    ===Issue (shell) commands===
    ===Direct installation===


    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.
    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.


    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).
    === Kommandozeilenbefehle auslösen ===
     
    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.

    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.

    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}}

    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

    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).

    Beispiel:

    was eingetippt? was passiert?
    gwe (startet 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 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

    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

    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

    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

    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!
