In that case I also think the keys I mentioned are the best.  Those are
* C-;
* C-,
* C-'
* C-=
* C-+

Here is why....  Those keys don't work on terminal emulators, at least
not without significant configuration of the emulator.  So, not only
does Emacs not use them, it's unlikely that the Emacs developers will
start using them for new features.

For example you could map C-; to switch windows in your windowing system
and map C-, to your input method program.

Another poster mentioned the possibility of using both shift keys
pressed together.  I think that's a good idea too since Emacs doesn't
use the binding or differentiate between left and right shift.  (Not by
default, I think it can).

Someone also mentioned the possibility of repurposing M-s.  Now I agree
that there isn't that much useful on M-s.  Personally I use occur (M-s
o) and isearch-forward-symbol (M-s _).  But remember that other things
could be added in the future and you'd be missing out on them.  Of
course, you could move the M-s keymap elsewhere so you can retain those
features but that's extra work.
