Readers who finish reading a page should always have good navigational links to get them to somewhere else useful. But not all material is strongly sequential. Sometimes you want to give the reader multiple ways out. For example, after learning about carburetors, you might have links like:
See also: Fuel systems; intake manifolds; air cleaners.
There is also the problem of what to do at the end of a sequential section. One popular option is to provide a link labeled `Up', which goes to the heading above this one in the tree. However, Dr. Jon Price says this is not intuitive, especially for readers who have jumped into the middle of your tree. He recommends that you have a link that does go up a level, but call it a `see also' link instead of an `up' link.
As with `next' and `previous' links, WebStyler can get `see also' targets from two sources: you can provide them explicitly, and WebStyler infers them from the file's position in the hierarchy. However, there is an important difference: a page can have any number of see-also links.
The root page, of course, will not have a see-also link. Also, there is a special form of the <see> link that suppresses the see-also link; see the page on `The <see> tag'.
