how2 get single char from keyboard w/o enter

I am writing a bash shell menu and would like to get a char immediately after a key is pressed. This script does not work but should give you an idea of what I am trying to do....
Thanks for the help

#! /bin/bash
echo -en "Choose item...\n"
until [ $ANSWER <> null ]
sleep 1
echo -en "You pressed $ANSWER\n"

Thanks, I found it! I had tried all kinds of internet searches for "bash input", bash press any key", etc and all I found was the standard "read" key routines. I had to do this about 3 years ago and had thought I used something like $keyin=<STDIN> but nothing like that has worked Smilie
