Capabilities are logical groups of related functionality that are used to perform a specific task, such development for a particular programming language. Welcome page selections determine what capabilities are enabled, but capabilities can also later be enabled or disabled using the preference page. When a capability is enabled, the actions associated with that capability are available to you, however once a capability is disabled those actions are no longer visible in menus, wizards and so on. If you attempt to employ an action that has been disabled a prompt will appear confirming the enablement of the action, thus providing new functions to the Workbench as they are required.
