I use ubuntu 20.04 with mate (then marco). Up to now (pre-20.04) I could bind Mod4+S to my liking (Win+S). After 20.04 upgrade I discover that this Key shortcut Mod4+S is kinda 'hard-coded' to run mate-search-tool, and my explicit binding from [ControlCenter][Keyboard shortcuts] is not honored (ignored).
The problem exhibit itself as marco spitting the following message
"Failed to execute child process mate-search-tool (No such file or directory)"
Or if I install mate-utils (that I don't need) it run mate-search-tool.
I double checked the decong editor (gsettings) for any hidden 'run-command' mapped on key Mod4+S key but could not find any.
So at the moment I call it an hard-coded key binding.
I'd like to bind Mod4+S, any pointers appreciated.
Cheers
