If you log in and turn on the icon toolbar, on the upper right you find icons for the most often used functions:

refreshes the current page
shows a printable version of the page without the header or footer
creates a XML version of the page (currently still experimental, creates StyleBook, a DocBook variant)
/ allows to subscribe to email notifications for the current page, the brighter version means you have already subscribed to a page
allows you to say something, i.e. edit the page
shows meta information about the page, especially the full version history
shows changes between the current version and the previous version of the page
shows the search page.
shows the help page
links to a user's homepage, if the user is logged in and a page with his login name exists

Clicking on the Page Title link located in the header above will show every page that references this page.

On the bottom of each page, logged-in users will find a link to edit that page.
