Is it possible to go to Resharper -> Options -> IntelliSense -> General and switch from Resharper to Visual Studio using a command in Resharper 5?
I would like to benefit from the Razor Intellisense which comes with ASP.NET MVC 3 RC but Resharper makes it look buggy (take a look at Scott's Tweet).
I don't know if is possible to to only turn ReSharper intellisense on and off. However, you can turn all of ReSharper on and off using a keyboard shortcut. On my computer it still takes a few seconds but it may be the best solution until the bug is fixed.
In Tools -> Options -> Environment -> Keyboard bind the ReSharper_ToggleSuspended command to a keyboard shortcut.
