redo as in undo/redo changes?? hmm - well, I'd assume you have to use some sort of data structure to hold data so you can "roll back" to what it was before. Basically, if you have undo written - you just reverse the process. Say undo holds each "change" which you could say decipher there were changes via messages - well, hold that data in a data structure - when you use 'undo' hold the information that was 'undone' in a data structure - when you redo, have it "rollback" - hope that makes sense, and helps with your algorithm a little bit
