Now, I just hit CTRL-S every few minutes or if I do something great.
Man, I'd lose time with this because I'd be hitting CTRL+S with every move I make, every breath I take...
Edit, but seriously, I also turned Autosave off for the same above reasons (not timed well / getting in the way) and just got into the habit of hitting CTRL+S at (or before) key points.
