enhancement request: have inverse of Info-last - as in Web brower Forward button

[Drew Adams]

Not a bug, but an enhancement request.

How about having a command that is the inverse of Info-last, say,
Info-forward. Info-last (it would be better named Info-back) and
Info-forward would act like the Back and Forward buttons of a Web
browser, taking you back or forward in the history of visited nodes.


In GNU Emacs 21.3.50.1 (i386-mingw-nt5.1.2600)
 of 2004-07-26 on BERATUNG4
configured using `configure --with-gcc
(3.3) --cflags -I../../jpeg-6b-1/include -I../../libpng-1.2.4-1/include -I..
/../tiff-3.5.7/include -I../../xpm-nox-4.2.0/include -I../../zlib-1.1.4-1/in
clude'

This is not possible with the `Info-history' variable since it
actually is a stack, not a list of all visited nodes.  However,
in CVS there is a new internal variable `Info-history-list' which
holds a list of all visited nodes and which is used by the `Info-history'
command (bound to `L').  You could try it and see if you still think
`Info-forward' is needed.

Yes, I'm aware of the stack being popped by `l', and the existence of `L'
and Info-history-list.

`L' corresponds to opening a History pane (frame) in a browser. It's not the
same thing as having Back and Forward buttons (keys).

For instance, I have `l' bound to mouse-4, which is bound by default in a
Web browser to Back. I would like to bind mouse-4 and mouse-5 to true Back
and Forward commands that navigate down and up Info-history-list.

I can no doubt write code for this myself, but it would be better to have it
in Emacs, for everyone.

Thanks,

  Drew
