My apologies for not being more clear.. I support the idea of there being an alternate break method, not specifically CTRL+C -- I was using that more as an illustration of something "simple and on just about every modern keyboard". As far as suggesting what key combo to use.. I like the idea of CTRL+END or maybe CTRL+BACKSPACE, perhaps?
Also, to the OP and others, another (temporary) solution has occurred to me.. if you can use software like AutoIt or AutoHotKey to "remap" your keyboard/keystrokes, you can pretty much map anything you like to send a CTRL+BREAK (which is what I'm doing now after thinking about it.. :-D)
