I remapped the modifiers on my keyboard such that the bottom row is Win - Alt - Ctrl - Space - Ctrl - Alt - Win This is so that I can use my thumbs for Ctrl and index fingers for Alt. I taught myself to use the opposite side modifiers every time (using the right control for Ctrl-S). This got rid of the vast majority of unergonomic keystrokes for me.
