m-sh-V

[Randy Parker <PARKER@MIT-REAGAN>]

In Symbolics 3600 Release 6.0, IP-TCP 29.0, AISite 9.7,
microcode TMC5-MIC 319, FEP 18, VisiStep, Rodent Free Namespace Editor,
Logical Pathname Completion patch, on PA Lisp Machine Merlin:

(tv:add-select-key #/Z 'zwei:zmacs-frame "Normal Zmacs Editor" t t)
                   ^^^
With the above line in my buffer, typing m-sh-V (albeit accidentally) at
either of the arrows got this error.
m-sh-V does the right thing everywhere else on the line, save
for on either of these:
   "Normal
    Editor"
