Hi,
In short, pressing ctrl+{other key} just sends a code that's 64 (dec) lower than then {other key} by itself. So ctrl-@ sends '0' (NUL), ctrl-C sends '3', ctrl-T '20'. To make it easy, no difference is made between upper/lowercase. Look at an ASCII table, as this method is/was meant to send codes from 0-31 (with 32 having its own key, spacebar), and you'll see why some non-letter {other keys} like '[' or ']' work, but others like e.g. '*' (usually) don't.
Regards,
Pieter
