Button bars are a simple navigation tool. They contain pointers to useful places, usually pointers back to root nodes of the hierarchy. Button bars tend to be useful because they are consistent navigation tools within the document. They should remain consistent over a broad range of documents, thus helping the user build a mental map.
The two sample icon bars are set up for Stanford CS departement, but the gist should be clear enough for you to make your own button bar files.
<!--#include virtual="/CS/Images/icons.pcd.inc" -->Of course, the file name would probably be different, and note that the included file must be on the same server as the document. It's not a good idea to try and include button bars stored on other servers. For one thing, it takes too long to load.
Since the <!--#include ... > is a mouthful for users
to remember to type, it is a good idea to include
this as part of the standard
template
file given to users.
The PCD include file and the CS dept. include file can be downloaded.
