Oleh Krehel has a nifty new package that brings ace-jump-mode functionality to links in help and info buffers. The package, ace-link, makes following links easy by putting letters in front of each link. You follow the link by picking the appropriate letter.
It’s available through MELPA so installing it is easy. The only thing you need to do is initialize the binding (‘o’ by default) by adding
(ace-link-setup-default)
to your .emacs or init.el file. Alternatively, you could set the key map manually and use some other key.
I just loaded ace-link and while I’ve played around with it, I haven’t used it “for real” yet. So far, though, I like it a lot. Just as ace-jump-mode gives you an easy way to jump around in your buffer, ace-link makes it easy to follow links.
