Sure: define a command that does both, depending on whether or not
there's a selection, then bind #k"tab" to that command.

C-h is actually somehat useful (sometimes).  (Try "C-h h" to see what
options C-h supports.)

Note that I'm not trying to claim that C-h is anything more than "somewhat
useful, sometimes"; it's a few notches above "completely useless" and 
several notches below "as useful as it could be."

C-h m describes all of the key bindings available in a named "mode"; it
doesn't describe bindings that're common to all modes.  (I don't know
of a way to do that via C-h.)

If all else fails, most (all ?) of the calls to HI:BIND-KEY that establish
key bindings are in "ccl:cocoa-ide;hemlock;src;bindings.lisp".
