Info Catalog
This (the Directory node) gives a menu of major topics.
Typing "q" exits, "?" lists all Info commands, "d" returns here,
"h" gives a primer for first-timers,
"mEmacs<Return>" visits the Emacs topic, etc.
In Emacs, you can click mouse button 2 on a menu item or cross reference
to select it.
