Re: RE: RE: RE: RE: Viewing Info Files - Introduce Top Menu also before end of buffer

So the lisp code can detect according to the system or there will be two 
versions
of the code, or whatever you have done.  I recommend putting a list of the 
keybindings
so one can easily figure it they interfere with those already set by the user.
