This macro allows you to create a link to another page with the same name in a different space.
For example, perhaps you want to version your documentation, so you create a copy. However, you want to have a link on each page that links to the latest version of the documentation (e.g. in the LATEST space).
All you need to do is to Insert this macro and choose the LATEST space, and your link will be generated.
