A guided tour of Emacs

I recently came across the GNU page: A guided tour of Emacs. It is a gem of an introduction to Emacs. Unlike the help distributed with Emacs (tutorial, FAQ, *info* pages), this tour does a good job illustrating the wide variety of Emacs capabilities, and I think it is much more motivating for a newbie than anything else I've seen.

Emacs Tip #24: view-emacs-problems

M-x view-emacs-problems

Like any good tool, Emacs can tell you about problems about which it knows. I just learned something myself (see 'Emacs pauses for several seconds when changing the default font').

To see the problems file, use the keybinding:

   C-h C-e
