toggle-new ... toggle-old ?

[hymie at nasalinux.net]

So this is probably a "just me" issue, but it can't hurt to ask.

I know there is a "toggle-new" keystroke, which lets me quickly go
through new email (flagged with an N) and "mark them as read" without
actually reading them.

But sometimes I end up with waiting emails flagged with an O .

Is there a single-key command, or a way to create a single-key command,
that will toggle this flag off the same way?
