With KDE you can set any key or a combination of keys to trigger an action on your computer. As an example: when I pause my work I want to lock my screen with the Pause key so my colleagues cannot baggy-pants me. Here is how to do that.

  • call the command systemsettings
  • select Shortcuts and GesturesCustom ShortcutsEditNewGlobal ShortcutCommand/URL and enter Pause


  • In the Trigger tab, click on None
  • press the Pause key
  • go to the Action tab
  • enter
qdbus org.kde.screensaver /ScreenSaver org.freedesktop.ScreenSaver.Lock

or (whatever works)


or (whatever works)

/usr/lib64/kde4/libexec/kscreenlocker --forcelock
  • click Apply
  • test it by pressing the Pause key
