If you want to use a 4 characters keyboard key as a shell shortcut,
you will need to use a different shell than OpenBSD's ksh.
Like GNU's bash.
As you found out, ksh can only use key sequence in the form of
prefix + (1 letter). You get no error defining prefix + (2 letters)
but the 2nd character is ignored.
Also, as you tested, you can define as many prefix-2 sequence as
you want, they all end up as synomym of each other though.
Like up arrow is defined by default as:
^XA = up-history
but the actual key sequence is ^[[A for the keyboard up arrow. It
works because both ^X and ^[[ are defined as prefix-2.
Basicaly in your first exemple, you defined ( prefix-2 + ~ ). Houray
for tilde, but that doesn't allow you to differentiate between all
the key codes ending with ~.
