use Win key for shortcuts

[Thomas Blasejewicz]

Good evening
Before I had to reinstall Kubuntu, I DID use the "Win" (apparently also
called "Meta", or "Super") key for shortcuts.
Like Win + T = open a terminal

After I reinstalled and fixed the recent "dependency problems"
this does not work any more.
Pressing Win + any key, opens a little window at the top of the screen
saying "System Activity".
That is wonderful, but I would like to use that Win key for a number of
shortcuts. (which DID work before)

Is there a trick to get that functionality back?

Thank you.
Thomas
