The program would operate by opening /dev/kbd, then binding its output
to /dev/kbd.
It would read a list of keybindings (from a file and/or command line options),
then operate in a loop of reading a key from (the old) /dev/kbd, checking if it
matches any of the bindings given to it. If it finds a match, it executes the
action associated with it. Otherwise, it passes the keypress on.
This could be used for global keyboard shortcuts by wrapping around rio,
or for per-program keyboard shortcuts.
`awk` is surprisingly close to working for this, but it has a few problems,
both with reading input delimited by NUL instead of LF, and with
non-printable characters in regular expressions.
I'm up to provide a bounty for this, although first I'd like to have a rough
idea of how difficult it would be to either write such a program, or to
fix the problems with `awk`, so I know how much a reasonable bounty
would be.

One of the easy approaches used in riow[1] is to catch all keyboard
events that involve a specific modifier, Mod4 in this case, export it
via fs, and convert to plain text form in another small program.
Those then are used to do window management.

> wrapping around rio,
Also the most correct way to write a screen locker. Right now if
someone has a rio with keyboard-based window management, they can just
close screenlock(1) with the keyboard.
