General Development "I was reading about vim the other day and found out why it used hjkl keys as arrow keys. When Bill Joy created the vi text editor he used the ADM-3A terminal, which had the arrows on hjkl keys, so naturally he reused the same keys." As interesting as that is, John Graham-Cumming goes even further back in history. "The reason that keyboard had those arrows keys on it was because those keys correspond to CTRL-H, J, K, L and the CTRL key back then worked by killing bit 6 (and bit 5) of the characters being typed." Truly fascinating stuff, even though it's from way before my time (I'm from 1984).

Personally, I have mixed feelings about VI. I do use it all the time simply because it's available everywhere and that makes it an essential tool. But VI's modes often get in the way of what my brain is thinking and I'd much rather use a stateless interface so my poor escape key can get some rest.


IIRC, VIM has an easy mode, something like -E option.


To be honest I find ESC to be even less "accessible" than arrow keys are


You can also use Ctrl-[ as an ESC equivalent.
