I agree. Gimp's undo and redo feature differs from many other programs in
that when comparing subtle changes it is useful to switch rapidly between
the "before" and "after" views, while for a program such as a word
processor, that is probably not a useful thing to do. This being the
case, this particular need of GIMP users was probably not considered by
Personally, I compare between the "before" and "after" by holding down
control and hitting z or r as necessary. For some changes, I switch
several times a second, as the human eye is remarkably able to detect
small differences when they are animated.
Switching between views this fast with accuracy is simply not possible
using Shift-Ctrl-Z due the the physiology of the human hand. The optimal
hand position is left on the shift and control and right on the z, with
the finger on the shift moving every other beat of the other hand and the
finger on the control key staying still.
Here the body's natural cordination works against switching views quickly,
as the nervous system will assume that the finger on the R key and
that on the shift key should really be synchronized. This leads to
errors. With the old bindings the natural cordination system helps to
acomplish the task accurately and faster.

Unfortunately, it is not. Really, GTK should be made more flexable in
this regard, but it is not a trival problem, due to how GTK handles
Since we only can choose one, it makes sense that we choose the one that
ergonomics favors. I'm sure that in this case most usability people would
say that actually being able to use the feature is more important than
consistancy with some other apps. Especially because this particular
funciton isn't particularly consistant between apps.
On the other hand, we could go for both ergonomics and consistency by
using MS Office's Ctrl-Y. Note that I am not recommending it. I think
keeping redo the way it is in 1.2 is the best policy.

There we go, between that and tradition, we have all the justification we
