I have probably tried 3 times to ditch the arrows and use hjkl and I've failed each time. What is the trick to overcoming this? Perhaps it's that I've done it while at work that has caused the issue (ie. I need to be productive now!). Pick a weekend and force the switch?
i went through the same pains. the worst was copy and paste. what a pain! but in a week or two it will become mostly natural.
