ActionScript 3.0 Language Specification

This document defines the ActionScript 3.0 language, which is designed to be forward- compatible with the next edition of ECMAScript (ECMA-262).

This document is complete in the syntax and high-level semantics of the language, but lacks details regarding features that have not changed from the ECMA-262 edition 3 specification, compatibility with ActionScript 2.0, and low-level semantics of some new features.

Sounds like you have the navigation frame hidden. Click on the "Show Navigation" icon in the upper-left-hand corner of the browser window. The navigation frame will then become visible on the left-hand side of the window.

The LiveDocs are very unfriendly. I would like to access the ActionScript Specification as a PDF format single file so I can use it as reference while I work with Flash designs.
