Defining own shortcuts

edit

You may not be happy with the predefined shortcuts but you can easily redefine existing shortcuts, or define your own. All you need to do is open KMenu -> Control Center-> Regional & Accessibility -> Keyboard Shortcuts. The interface of this is self-explanatory.

Here is the list of thing you may do with defined shortcuts:

  1. opening apps very quickly,
  2. kill, start, restart daemons,
  3. send commands to running apps...
