how to have no interpretation of special characters (ctrl, tab ...) in a script

Hello,
does anyone know how to disable interpretaion of special characters in a script ?
I would like to get a script that breaks whenever I press any key of the keyboard, for say during 5 seconds.
I have the following script.

Code:

i=5
while [ $i -ge 0 ]; do
  tput cub1
  echo -n "$i"
  read -n1 -t 1 keypressed <&1
  if [ ! -z "$keypressed" ]; then
    echo "stop"
    break
  fi
  let $[ i -= 1 ]
done

It is ok when I press alphanumeric keys, but it doesn't work for keys like "tab" key or "ctrl" key.
Any help will be very appreciated.

Thanks, xround

The keys you describe are configured as Modifiers in your X configuration. Reconfiguring the keyboard so that they are not modifiers anymore is the only clean solution I see.
I think this reconfiguration can be done on a per-application basis using xmodmap (or is it something else?)
