I love Ctrl+Click but its behaviour as subtely changed recently.
In previous builds Ctrl+Click on a definition (E.G. a parameter) selected the entire token. I found this to be a useful way of easily highlighting the entire token.
In build 423 R# attempts to jump to the definition, which is a no-op as I am clicking on the definition.
The only observable side effect is the line that is clicked scrolls to the centre of the screen. Interesting, but not as useful.
Please consider bringing back selecting the token on Ctrl+Click if the token is the definition.
