When & why does that need to be explained?
Is there a missing binding, perhaps?

That's an orthogonal problem, which is not
specific to context menus, right?  That's
a general, longstanding problem, IIUC.

Is there a reason why one has and the other
doesn't have a binding?  Does it matter?

How is this related to the general question
of whether _context menu_ items should be
able to have keys listed?  Doesn't all that
you wrote apply to menus generally?
