I need to send CTRL+[char] code to a terminal using JavaScript. So it’s not a question of capturing it – I can detect CTRL down and I can detect a character key pressed, and if it was just for something that needed done in JS I’d be all set. However, I need to send it, as one character code to a terminal and I can’t find for the life of me what the code for CTRL+[char] would be.

In this specific case I need the code for CTRL+Backspace combination, but I thought I could find, in the sea of internet, a table that lists all those keycodes, including CTRL+C/V/P, CTRL+Enter, and so on. No such luck though (I guess I still need to work on my Google-fu).

Anyone know this?

    There’s no such keycode – the keycode is always a single ascii character, in your case [char]. Note: if you press ctrl+v, first an event with keycode=ctrl is sent, and then another one with v.

    The thing you’re looking for is shiftkeys (afaik).
