Showkey

Display cooked key sequences (keycap-to-keystrokes mappings)

This program puts your terminal in raw mode, eats keystrokes, and prints them back it you in a recognizable printed form using <>-surrounded ASCII mnemonics for non-printables.

This may be useful, for example, if you’re not certain what your keyboard keys are sending.
