0. Visual Studio 2010 rc (30128) (on Windows 7 x64)
1. Install R# 5 RC (update previous beta with default installer settings)
2. Turn on CamelHumps selection helper
3. Try to select text by pressing Ctrl and Left/Right keys
It selects only N+1 nearest words to cursor. (where N is count of selected words before starting selection with Ctrl key)
Looks funny, but only for few minutes...
I've recordered a screencast to show how it looks: http://vimeo.com/10435948
