Is familiarity an argument when what's "familiar" is *way* less
comfortable than the less-familiar but better shortcut?
IMHO needing <shift> to toggle between undo and redo is an
absolute usability desaster. The reasons have been said earlier
in this thread: repetitive undo/redo is a a common operation in
graphics applications, unlike e.g. text editors.
I completely follow the rationale of consistency but IMHO
usability overweights it.

Yes, and more applications are text editors or word processors
or similar things where this absolutely makes sense. Is it our
fault that the HIG guys only have GEdit in mind when they write
And btw, a considerable percentage of mails in this thread
voted for ctrl+R, does this count less than questionable

I guess people will rather find it annoying to do complicated
<shift> trick using three instead of two fingers. Have you ever
looked what photoshop *really* does when pressing the undo
shortcut several times? Following them when it comes to undo
key bindings is the worst we could do...

I don't know about others' doubts, but I have no doubt that we should
keep <ctrl>+R, since we are not talking about feature xy of
application xy (how often do you use undo in your word processor), but
we talk about the most-used shortcuts in the GIMP. Making them
less accessible is no option IMHO.
