Navigating and Customizing the Flex Builder Workbench
The term workbench refers to the Flex Builder development environment. The workbench contains three primary elements: perspectives, editors, and views. You use all three in various combinations at various points in the application development process. The workbench is the container for all the development tools you use to develop applications.
