You will now be asked to press in turn each of the 12 function keys, then
the Backspace key, the 6 common keypad keys found on typical PC keyboards,
plus the 4 arrow keys, and finally the Menu key (near Ctrl on the right).
If your keyboard does not have the requested key, press Space to skip to
the next key.
Do not type ahead! Wait at least one second after pressing each key for
zsh to read the entire sequence and prompt for the next key. If a key
sequence does not echo within 2 seconds after you press it, that key may
not be sending any sequence at all. In this case zsh is not able to make
use of that key. Press Space to skip to the next key.
