You can now set a preference for F1 destination in most CS4 products

Just so you all know, most of the CS4 products, with the exception of Flash and After Effects, send you to their Help & Support homepage by default when you press F1 (Help Menu > Help). Well, you can now set a preference in the main page of those products’ Help systems to send you directly to the Web Help system from F1 instead of the Help and Support page.

Details are available here and here. This UI is the same for all the products that default F1 to their Help & Support page.

Also, remember to click the “This help system only” checkbox when searching within a product help system if you want only results from the help for that product. Otherwise adobe.com and community results are returned by default.
