When using   "read -k key"

I am matching against normal keys with
if [ $key = '?' ]

simple control characters like tabs with
if (( #key == ##\t ))

Ctrl + key sequences with
(( #key == ##\C-u ))

But how do I match against Alt + key sequences?

Thanks,
Wendell

Then it's unrelated to bindkey ;-)

Try this:

while [ : ]; do
    read -ks a
    [[ $a = ' ' ]] && foo
done

Have a look at “man zshbuiltins” for more about the “read” builtin.
