Since it's a big part of my field of study, I've gotten very used to the Mac-style way of going back and forth in the history that is in Adobe applications: Ctrl-Z for Undo, and Ctrl-Shift-Z for Redo. It's much easier this way, I find, and most importantly, since I don't use such apps as often, I always get mixed up where the shortcut for Redo is Ctrl-Y, such as Microsoft Office.
And worse yet, sometimes, there's something else on Shift-Ctrl-Z. So I go back a few times (Ctrl-Z), copy some part I had right at that moment and later deleted, and do Shift-Ctrl-Z to come back to the "present" state. And then whatever Shift-Ctrl-Z does in that app is done, which destroys all "forward" steps I had. I have just lost my progress.
It's really frustrating, and causes issues. I just can't get my brain to remember "hello, you're presently in X, so don't go pressing Ctrl-Shift-Z!"
So considering this, and the fact that it's a huge pain in some apps to change shortcuts (like Microsoft Word for example), as well as the fact that I often work at school on Deep Frozen computers and don't want to spend half of the allocated time for in-class work/exams going around apps editing shortcuts, I wonder if there's some sort of global/simpler, ideally quick, solution to this.
Ideally, the solution should work on Windows Xp as well, since some of my classes will probably take place in the outdated, ugly Windows Xp computers room.
It doesn't have to do exactly what I said, but if you have an idea that would help solve my issue, I would be grateful.
Also, it's much less important, but if the above is possible, is it also possible to do the same kind of global operation to have commands such as Save As the way I'm used to? (Ctrl-shift-S)?
