    In ZWEI in Release 5.1, Experimental MIT 1.4, COLOR 5.1, FEP 18, on Lisp Machine Buddy Holly (3600):

    The sequence C-s c-Q c-G ends up searching for G rather than c-G, contrary
    to the documentation given by <help> during a C-s search.

There is no such character as c-G in the character set that can be placed in files.
The control, meta, hyper, super modifiers can only be entered from the keyboard;
they cannot be stored in files.  But maybe there is also a bug: what character were
you actually searching for?
