The "Up" Button

Syntax: .UP URL= [Label=] [Target=]

The Up button belongs to a row of controls that are used for navigating through multi-page documents. Its purpose is to take the reader up one level in the structure of the document, for example from Section 1.1 to Section 1.

Defining the Up Button's Function

You can specify the behavior of the Up button with the following command:

.UP URL= [Label=]

For example:

<!--.UP URL="section.shtml" Label="Beginning of Section"-->

Normally, the Document Interface program will construct the Up button as a text button of the form:

Go to "ButtonLabel"

The Label parameter is optional. The default value of Label is the title of the document pointed to by the URL attribute.

The Target parameter creates a link that points to another window or frame. Use a value of _parent to break out of frames, _blank to open a new window with the link, or another name of your choice to refer to a particular window or frame.
