Sometimes when a page is dislpayed, terms may be present next to the page title that can be clicked on to get a list of other related pages to your current page.
For example, the LPC11xx device information page provides information specific to the LPC11xx device, but also has a list of terms next to it similar to "i2c, spi, uart, ..." next to it. For the LPC11xx device, these terms provide an association between the microprocessor and various interfaces or peripherals that are used on that device. Clicking on one of these terms will take you to a dynamically generated page with content on it about that related topic. The generated page may contain FAQ pages, drivers, etc.
This provides a powerful method for searching for related content as an alternative to the search function.
