The following words produce the same values that EKEY produces when the user
presses the corresponding key.

K-LEFT ( -- u ) facility ext
The "cursor left" key

Depending on the terminal, key codes generated after pressing one
single key can be several characters long. I doubt that this will
always fit into one u number.

I don't know if that is what is intended by the proposal, but EKEY
could catch those escape sequences and translate them to unique
16/32/64 bit numbers, e.g. this K-LEFT constant.

The Gforth implementation actually works that way.
