not abled to when cmd + z pressed & can we disable cmd + z completely from editor?

Hi,

I can't able to track cmd + z pressed in anywhere since i want to perform some actions when undoing changes, i have acheived that with undo manager when i click on undo button but i can't do with cmd + z, is there any way to do this?

Or i just want to restrict the ctrl + z option since have undo button in editor itself, is that possible?

Thanks
