Describe the bug
When using Wayland instead of X11, the global shortcut engine does not work and as a consequence none of the user-registered shortcuts function.

Steps to Reproduce
Steps to reproduce the behavior:

1. Use Wayland
2. Try to use or register a shortcut

Expected behavior
Shortcuts to work normally

Desktop (please complete the following information):

• OS: Linux (Wayland)
• Version: all

Additional context
To my knowledge to this date Wayland (in contrast to X11) does not provide a way to either grab all user input nor does it allow to register global shortcuts. Instead one is supposed to register shortcuts with the currently used Window Manager (but there does not seem to exist a standard to do this).
