I believe I already agreed to that.  We even had a patch posted for
it, and I commented on it.

We need more opinions for this one.  If many people agree to it, I
won't object.

If you can find a good key that is vacant, sure, why not?

Since we don't have any profiles yet, this is not something we can do.

Having said all of the above, I'm now asking myself (and you) why do
we have to have a special mode for this?  None of these measures
contradicts the default operation of undo via C-/, so we could simply
have this by default.

If the user uses the menus or the tool bar, the confusion will be
spared, right?
