The following content is an organic document of tips and tricks when using Flex builder (v2) which I’ve picked up here and there.
Misc shortcuts

Quick Outline
There is a Quick Outline view in the code editor (source view). Press Control+O to access:

This view displays the classes and their members, you can begin typing to quickly locate and highlight the relevant code.
Code Definition
To view code that is located outside of the document that you are currently editing. With the cursor, select the component and press F3. The class file that contains the components definition will open in the editor.
Language reference help
Place your cursor in an element (like Label) and press Shift+F2, a help popup will open containing reference topics for the highlighted component.
Components view
When in the components view (in design mode) you can simply start typing the name of the component you want and Flex builder will highlight the relevant matches.
