I know this thread is a little off-topic, but since most of C++ programmers use emacs, I think this question is interested by many C++ programmers:
Suppose you have 5 splitted windows and you are in window 2. You want to switch to window 1. I know a way to switch to the next window is Ctrl-x o, but you have to switch 4 times to window 1. Is there a way to switch counter-clockwisely?
