Exploring KRunner's Functions
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.
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)
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.
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.
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.
10 acres will output 40469 m².
