I assume that ``forceme'' uses TIOCSTI to simulate terminal input. For
readers without it, enclosed is tiocsti, which does the same job.

Right. Btw, why don't you use \' rather than "'"? Might not work in
awk, of course, but if you're just interested in being a lazy typist...
Actually, it'd be a lot clearer to just double-quote your entire alias.
