...as:

1) NOT allowing removal of any keyboard shortcut involving a keyboard
key that has an XO-specific image/glyph (this reserves all the F-keys,
and the XO-only keys on the keyboard and monitor like search, overlay,
rotate, dpad, etc.) and/or are obviously required for minimal sugar
functionality (this reserves ctrl-esc for exit/quit activity and
alt-tab and ctrl-alt-tab for obvious window-switching features) - this
is all justified, IMHO, by eben agreeing with bemacs's
"only a handful of special keys should be trapped by sugar, to ensure
minimal functionality . . ."; and

2) allowing removal of any keyboard shortcut that is not required by
minimal sugar functionality - this is all justified both as the
converse of what eben's agreement with bemasc means and also as a
consequence of eben explictly not objecting to removing the Ctrl-O
shortcut ("I wouldn't be sad if [the ctrl-o/open] shortcut went away").

The only contentiousness I can possibly see (if I've interpreted
eben/bemasc sympathetically) with this patch is that non-XO users of
sugar could lose access to the functionality now only available with
the XO-only keys (e.g., rotate, overlay).  I argue 1) this is not a
concern for any deployment; and 2) this can easily be addressed by
choosing different, less likely-to-interfere shortcuts.  As I'm less
comfortable choosing these shortcuts and without these shortcuts all
deployments can still make full use of Sugar/XO, I will defer any
choice of these alternates to a different patch so this patch can
easily be cherry-picked.
