+ possible to handle terminals where the keypad only works in
+ local (this applies, for example, to the unshifted HP 2621 keys).
+ If the keypad can be set to transmit or not transmit, tive these
+ codes as smkx and rmkx. Otherwise the keypad is assumed to

+In the st case smkx=\E[?1h\E= and rmkx=\E[?1l\E>, so it is mandatory that

+solution for them is to use the following command:
+ $ echo ^[?1h^[= >/dev/tty

+In the case of bash it is using readline, which has a different not in its
