KRunner is een hulpprogramma voor het zoeken naar bestanden en programma's en het starten ervan. Het kan ook gebruikt worden als calculator of voor conversie van eenheden. Op de meeste systemen kan KRunner geactiveerd worden door de toetscombinatie Alt+F2 te gebruiken..

Basic control

KRunner starten

There are several ways you can open KRunner:

  • Press its global shortcut (Alt + F2 by default)
  • Right click on your Plasma workspace and choose Run Command...
  • Run "krunner" command from a console

Krunner syntax

The '?' icon to the right of the entry field explains the syntax of each of the activeRunners. Scroll to see all the possible keywords and syntaxes that Runners recognise.

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

Als rekenmachine gebruiken

You can use KRunner as a calculator. Just open KRunner 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.

It is possible to evaluate more sophisticated expressions such as: =sqrt(4) + 32 * sin(60)

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 blog post. Additionally, a list of the supported functions is provided here.

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. For applications that appear in the applications menu, you may type a portion of the application name or keywords from its description. You may also use the names or descriptions of individual control panels to launch them.

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.

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

cp ~/Documents/myFile ~/myFile (not a useful example but you get the idea)

Launching websites

Enter a URL - http://www.somewhere.com - and the page will pop up in your browser.

Using web shortcuts

You can also use web shortcuts with KRunner. Example: gg:some-term will bring up Google search results.

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 writing Web Shortcuts in KRunner.

Eenheden omrekenen met KRunner

KRunner kan u helpen getallen te converteren van de ene eenheid naar de andere voor oppervlakte, lengte, massa, snelheid en volume in KDE SC 4.2 en valuta, energie, druk en temperatuur in KDE SC 4.3. Voor elke categorie is een standaard eenheid ingesteld.

Example: 6 feet in meters will output 1.8288 m.

When you don't give the target unit, conversion is done automatically into default unit of the category.

Example: 10 acres will output 40469 m².

Controlling Power Management via PowerDevil addon

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

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

Windows

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.

Advanced Usage with Single Runner Mode

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.
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.
