[Question] How to disable the key binding Alt-`?

[netjune]

It currently switches between windows of the same application. This key binding conflicts with my app. I want to disable this key binding in cinnamon. But I can't find where it is in setting center.

For some reason it's displayed as 'Alt+AboveTab` in the keyboard bindings:

Click on the binding entry in the lower pane, then Backspace to clear it.
