Hmmm.  The semantics I was aiming for are:

CTRL - "primary" shortcuts...standard/basic actions eg. "copy"
ALT - "alternate" shortucts...modifications of the corresponding
primary shortcuts, eg. "copy and erase" (cut)
SHIFT - "invert"...do the opposite of the primary or alternate
shortcut it is chorded with, eg. "cycle through open activities in
reverse"

My goals for the semantics never specified that different keys should
have different contexts or scopes.

Of course, now that you point it out, I think that ctrl-esc might be
the only global non-ALT shortcut.  So if others argue strongly against
using ctrl-esc, I'll leave it to a democratic decision.
