⌘Q is too damn close to ⌘W

Huh? I never had that problem and do actually like it that way. Train yourself to use the middle finger for "W" and the ring finger for pressing "Q" and the problem vanishes. It will still happen to you perhaps once per month, but I can live with that.

Huh. I guess that's true, for some reason I've never noticed it before.

I usually keep my left hand on my "home keys" when browsing (Firefox user here), in order from pinky to thumb, q-w-e-f-⌘, of which I use w, f, and ⌘ on a regular basis, and I guess that usually keeps me from mis-hitting q when I mean w, I'd actually have to push the wrong finger, which is pretty rare.

Right thumb goes on the trackpad for mouse interactions (much easier now that the MBP trackpad presses in rather than having a button), other four fingers on that hand go on j-k-l-; (⌘+j/k/l I use all the time for downloads/search/address bar, ; is wasted, of course). Scrolling is the only thing that sucks, but you can get pretty far with space/shift+space (hit space with left thumb, shift with right pinky).

If I had a problem with this, I'd probably go with the WoW shortcut for quitting, alt+command+Q, which is pretty hard to do accidentally (Double-thumb keypress? Expert move...) and doesn't tend to be bound to anything else. Command+1 seems like a bad idea because some of us are very used to Command+(number) to switch to tabs.

I just did this to a blog entry after reading your post. I should have written in out in vim like I normally do.

I think the worst design decision was putting the print button next to the save button. I've definitely sent code files in excess of 50k lines to some unknown printer before by accident.
