    site configuration 8, 210.80 MacDaed, on Marvin:
    ^Q ^F, for example, just gets treated as an F.
The character C-F takes more than 8 bits.  It therefore cannot be in a buffer
to search for.  The "ascii control" character  can be searched for without
any special quoting.
						    Also,
    is there a way to make case be a factor?  (ie, F <> f)
Do M-X Set Variable
Alphabetic Case Affects Search
