Making F1 do something useful in Visual Studio

There is a very easy alternative to this in VS 2010 now :) Go to the Help menu, select 'Manage Help Settings', ignore any error messages ( I get 'You do not have permission to modify content under the location specified for the help content store'). Anyway, ignore any error messages then in the window that pops up select 'Choose online or local help' then select the option 'I want to use online help' and then click okay and exit the window. And your done! VS will now open up a new tab/instance of your default browser and bring up a useful MSDN page with many search terms to get you right lanuage, version of .net framework, and lots of other things to get you good results, just from highlighting what you want and clicking F1 :)
