here's what i think. in both ijkl and hjkl, you have one finger doing 2 keys. In vi, it's pointing finger doing hj, moving side ways. In ijkl, it's middle finger doing up down. So i think ijkl is slightly better. I remember seeing similar analysis on coleman forum.

I see what you mean about the 1 finger 2 keys bit, but I find I tend to either be moving up and down lines or left and right in a line. With HJKL I'm then using two separate fingers for navigation horizontally and vertically. If I used IJKL I'd be using a single finger when moving vertically and two fingers horizontally.

I'm curious as to what people who spend more time in vim than I do think about that. Personally it seems more comfortable to be using different fingers rather than shifting when going up/down.

I'm not a vi user, but wouldn't you shift your hand one key to the left when navigating?
