Undo?

[mgrider]

I don't really use the mouse, so occasionally I'll hit the wrong number, and need to undo what I just did. My instinct is to hit cmd-z (I'm on a mac), but that doesn't actually work... but what if it did?

Also, once or twice I've started down a path, adding or removing notes, and then realize that I was mistaken, and wanted to undo a few moves in a row, so it should probably be a full undo buffer if possible.

This is kind of an over-the-top request, I know, but I thought I'd file it anyway. 😁
