All Mac applications use ⇧-Cmd-Z to redo the last undone action. All, that is, except Microsoft Office. Office prefers that you use Cmd-Y instead. ⇧-Cmd-Z is mapped to something else – worse, it's something which seems to be un-undoable based on my repeated accidental hits of it.
I've gone into Tools → Customize Keyboard but Redo doesn't appear in the (unsearchable) list anywhere. I can't find the mapping for ⇧-Cmd-Z either so that I can reassign it to something innocuous.
Does anyone know of a hack I might employ to 'fix' this behaviour and force Word (and Excel) to behave like good little Mac programs? Failing that, can anyone tell me what ⇧-Cmd-Z is mapped to so that I might disable it?
