Wrong shortcuts-keys in Ubuntu 18.04

  • 772

Description:

I have some keyboard shortcuts-keys that do not behave the correct way in some programs.
For example in Gimp, when pressing Shift+Ctrl+E: it should open the "export image" window to save the image.
Or, when I want to take a screenshot of the active windows, the Alt+Prnt Screen combination is taking a screenshot of the Unity search bar (which wasn't open at all at that time.).

Question:

Why are these shortcuts wrong and how to get them back properly?
I don't want to search for and list more examples here, but I am pretty sure I will encountered some others in the future.

Details:
I'm using a fresh install of Ubuntu 18.04: 4.15.0-42-generic x86_64 GNU/Linux with Unity: 7.5.0.

Update:

xev outputs:
