If you prefer to see help content in the browser instead of the Adobe Community Help application, do the following:
- Open Adobe Community Help
- Edit > Preferences
- Select “General Settings”
- Select “Open Help in browser”
Beware that this will affect all Adobe applications, not just Flash Builder.
Users of prior versions of Flex Builder are accustomed to opening the language reference in a browser. I should point out that for the Flex 4 SDK, available ASDoc content appears in code hints, tooltips and in the ASDoc view that appears in the default Flash perspective.
