KRunner est un outil de recherche et de lancement de fichiers et applications. Il peut également être utilisé pour des opérations plus génériques comme une calculatrice ou un convertisseur. Sur la plupart des systèmes KRunner peut être activé en appuyant sur la combinaison de touches Alt + F2.

Contrôle de base

Syntaxe de Krunner

L'icône '?' située à la droite du champ d'entrée explique la syntaxe de chacun des Runners actifs. Faites défiler pour voir tous les mots clés et syntaxes possibles reconnus par les Runners.

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.

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

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 writting Web Shortcuts in KRunner.

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.

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.
