That reminds me, I consider losing arrow keys a dealbreaker. I use them frequently enough to navigate both text and code in various contexts (except in Vim, which I don't use exclusively). I already hold modifiers to jump to next/prev word boundary, page, start/end of continuous data ranges in Excel, etc. Admittedly, I'd probably adapt, but I'm held back by the belief that any ergonomic advantages of moving to wasd or hjkl would be wiped out by reduction in speed and muscle memory for me.
