Control-Meta-, and Control-,

[Mike McMahon <MMCM at MIT-AI>]

In my environment, i assign GLS' buffer commands to C-X C-H and C-X C-M-H, which i find
quite satisfactory even though two keystrokes.  (I put something else on C-, and C-M-,.)
I put the ZTOP activation command on C-CR.
I therefore do not care about what the default is, so perhaps someone else can come up
with a nice complete scheme.
