> I don't use arrow keys to move around in text anymore but forced myself to use h, j, k, l. Many people say that this is faster. After trying this for a few years, I don't think that is true (at least for me). I now just stick to it out of habit. Sounds like he's not a touch-typist. And as a general note; learning and mastering vim can hardly be a pleasant activity for non touch-typists, or otherwise typing heroes.
w and b are faster because they move you horizontally between words, so pressing w 5 times will get you to the fifth "word" on a line, and b will go backwards. You only really ever use h or l after getting to the "word" you want, then going over to a letter using h and l.
I still mostly use j and k to move up or down lines
