Each time you display a new topic, the help system remembers the previous
topic so you can go back.


<procedure>To backtrack to the previous topic:

<list bullet tight>

 * In a general help dialog, choose Backtrack from the Navigate menu (Ctrl+B).

 * !!Or,!! in a quick help dialog, choose the Backtrack command button.

<\list>

Repeat Backtrack to go back as many steps as you need.

<note><head>Shortcut:  The Popup Menu

  The commands in the Navigate menu -- including Backtrack -- are
  duplicated in a popup menu.	To display the popup menu, point to the
  help display area, the press mouse button 3.	(On a two-button mouse,
  press both buttons simultaneously.)

Most hyperlinks are used to provide shortcuts to related topics.  That is,
the typical hyperlink "jumps" to another help topic.  Usually, the related
topic is displayed in the same window, however, some links may use a new
window.

<procedure>Graphics as Hyperlinks

Graphic images within help topics may be hyperlinks.  Unlike text, however,
the graphic is not underlined if it is a hyperlink.  Generally, the text
associated with a graphic tells if the image is a link.

<procedure>Hyperlinks that Performs Actions

Some hyperlinks perform actions (rather than jumping to another topic).
For instance, the following link starts a program: <link "xclock &"
Execute>Display X Clock<\link>.

For help windows displayed from within an application, it is also possible
for a hyperlink to invoke some application-specific behavior.
