Menus
*****
"Menus" contain pointers to subordinate nodes.(1) (Note:Menus-Footnote-1) In Info, you use menus to go to such nodes. Menus
have no effect in printed manuals and do not appear in them.
By convention, a menu is put at the end of a node since a reader who
uses the menu may not see text that follows it. Furthermore, a node
that has a menu should not contain much text. If you have a lot of text
and a menu, move most of the text into a new subnode--all but a few
lines. Otherwise, a reader with a terminal that displays only a few
lines may miss the menu and its associated text. As a practical matter,
you should locate a menu within 20 lines of the beginning of the node.
