You can create several types of links in a document:
A link to another document or to a file, such as a graphic, movie, PDF, or sound file. (See Linking files and documents.)
A named anchor link, which jumps to a specific location within a document. (See Linking to a specific place in a document.)
An e-mail link, which creates a new blank e-mail message with the recipients address already filled in. (See Creating an e-mail link.)
Null and script links, which enable you to attach behaviors to an object or to create a link that executes JavaScript code. (See Creating null and script links.)
NOTE
Before creating links, make sure you understand how document-relative paths, site root-relative paths, and absolute paths work. (See Understanding document locations and paths.)
