I'm running MATE Desktop 1.24.1 on openSUSE Tumbleweed.
There is a keyboard shortcut Alt+7 which acts similarly to Alt+Tab, but it switches between open windows in the same group. For example if I have multiple Firefox windows open, I can switch between them sing Alt+7 (see screenshot). I would like to disable this shortcut as it conflicts with another shortcut in one of the graphical programs I regularly use.
I checked all options in MATE's keyboard shortcuts preferences, but I didn't find any action with Alt+7 listed there. I also checked keyboard shortcut settings using dconf editor under /org/mate/marco/
.
In the windows switcher panel applet's Window List Preferences window, I have "Never group windows".
So far all my attempts have failed to disable Alt+7. Do you have any idea how to do that?
