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).

Other editors will (sometimes) warn that the file changed while being edited. But the upload and overwrite trick never does.

I agree you need a (editor-agnostic) 'check whether the file changed while I was working in it'. Of course you can have that with editors that do 'upload and overwrite' too.
