hjkl, after disabling arrow keys for a few months. If you don't use
hjkl, I think you should try it because it's a lot easier to get used to than you might think. You just have to dive in to the deep end and practice.
There are some interesting points raised in the discussions, like this one by Syfrix:
I've never officially learned to touchtype so I'm not familiar with the "right" positions of my fingers. I have four of my fingers on hjkl and that works fine for me. Interestingly, the default configuration of the i3 window manager uses jkl; as directional keys. I changed this to hjkl to make it consistent with vim and my browser, but maybe you'd want to try it out on vim?
But then Sphaerophoria said:
You shouldn't be doing single character motions enough that you need to move your hand over.
Which fits in with Drew Neil's idea about trying to make repeatable edits.
I don't mind moving my finger over to
h, so I don't think I'll ever leave
