How to get a keypress?

[Lars Eighner]

The ncurses functions are such a mess (and some of it I suspect is in
ncurses itself) that I am thinking the easiest way to write a terminal
interface is simply to write ANSI directly to the terminal.

Although the manual on the CLI refers me to readline, readline doesn't
seem provide a way to get a single key press, and so far as I can tell
doesn't provide a reference to how to get a single keypress. I reckon
some widgets would be more spiffy with keypresses instead of whole lines.

If you're on Windows, you can't. You have to press the enter key to
'send' the input. Unix/Linux it's supposed to work as expected. Haven't
tried it yet though.

HTML provides a way to get a keypress. Usually this can be
done with javascript or HTML inside the <headsection or
HTML inside the body. I've not messed with it, but have seen
it in other folks code.

If he just wants a way to provide client-side control, it's
called accesskey in HTML-speak.

That combined with some javascript to do an automatic POST,
probably can get the OP where he wants to go.

The OP is in a terminal (cli) window... no browser.
