Sorry, I don't understand: what is CAPS? is it the CapsLock key?

It's not always up to Emacs: some systems, notably a character
terminal, hide this in their low-level OS routines, so Emacs never
sees the raw keyboard events.  We should try not to use features that
are only available on some terminals.

If CAPS is CapsLock, Emacs doesn't see it at all on many platforms.
