Pessimistic: "without the full set of keyswitches, you need to use fancy tricks to make shortcuts usable".
Optimistic: "with fancy tricks, you can make shortcuts easily accessible without the need for the full set of keyswitches".
e.g. on my keyboard I have shortcuts for "goto desktop left" when I press "cv", (and "goto desktop right" when I press "m,"). This is more complex than a standard keyboard's Ctrl+Shift+Right (or whatever, as varies per OS), but it feels so convenient.
