Re: customizing a variable named in Info

[Richard Stallman]

    It would be nice to have a way to identity an Emacs variable in texinfo
    sources such that when Emacs Info renders the page it can make the
    variable name clickable in order to customize it.

In Texinfo, we use @code for variables and for functions, and for
other things.  You could imagine arranging to make @code cause Emacs
to check whether the name is a function, and whether it is a variable.
But this would require a change in Info format, which would be a real
pain.

Another idea is that Emacs Info could do something special when it is
looking at a manual that concerns Emacs, driven by the textual
context.  If it uses the existing format of Texinfo files, we only
need some convention for a magic cookie to put in the manual to enable
this feature.  The only hard part is to implement the feature in Emacs
Info.

Please work on it if you feel the urge.
