A cross reference can be placed anywhere in the text, unlike a menu item which must go at the front of a line. A cross reference looks like a menu item except that it has `*note' instead of `*'. It cannot be terminated by a `)', because `)''s are so often part of node names. If you wish to enclose a cross reference in parentheses, terminate it with a period first. Here are two examples of cross references pointers:
*Note details: commands. (See *note 3: Full Proof.)
These are just examples. The places they “lead to” do not really exist!
