Gregory's Server@b0rk That is also another hint for the 'j' in vim: go down one line, just like ctrl+j does in a terminal. Or is this just a coincident?

@bartavi @b0rk Likely coincidence. Have a look at "man ascii" and look at characters Decimal 1 to 26. Those are for the most part what you will get if it doesn't already do something special (like Ctrl+C). For example, Ctrl+H is character 8, which is backspace (but only the backspace character). Ctrl+I is a tab, and Ctrl+J is a newline '\n'. (This means Ctrl+M is actually a carriage return '\r', but your os likely translates both into '\n' in the input that your terminal programs receive).  |
@bartavi A bit of both plus a decision by an early terminal manufacturer. https://catonmat.net/why-vim-uses-hjkl-as-arrow-keys
ASCII had already defined the codes and 8 (aka ^H or backspace) and 10 (aka ^J or linefeed) already had a kind of intrinsic left- and down-ness to them. 11 and 12 (^K and ^L, or vertical tab and formfeed) kind of implied motion, but had more meaning when terminals printed to paper rather than a screen.
The folks at LS decided since your fingers were already there, why not complete the arrow set.
