Supporting the cursor keys is -- as far as I know -- a non-trivial
thing, because they do not generate one ascii character, but two (on
an ANSI terminal, they would be ESC A to ESC D, if memory serves
right). So the whole affair gets a little bit more interesting,
because if you read an escape key, you do have to look for a second
character. But what if the user just pressed the ESC key? You're not
getting a second character!
What I'm trying to say: I don't know if it's worth to go into
all that trouble just for the cursor keys. A lot of energy goes into
those things to have them behave just right, but there are so many
other keys to choose from, that I personally would think of that as a
waste of time. But that's just my very personal opinion.
