Basic
To add the link, add a  with type parameter set to   or   on a wiki page. Example: This outputs the default link text "&#171; Go Back".

Custom Text
For custom link text, use this code (link text can be anything): This outputs the link text "Go Back 1 Page", or whatever is between the opening and closing tags.

The "go" Parameter
Use this code to go back 3 pages, or whatever "go" is set to: Note: The "go" parameter can not be less than 1!

CSS Styles
The tag also has a "style" parameter that can contain CSS style information. Example: This will output a link that looks like &#171; Go Back.
