Spotter - could ignore message parameters

I find that I often copy a long keyword message like this...

      dispatchEvent: anEvent with:

But Spotter gets confused by the "anEvent" parameter, and even spaces,

so I have to edit all those out. 

It would be cool if Spotter was smart enough to ignore any characters 

that don't parse as part of message syntax.

also btw, is there a keyboard shortcut to open Spotter on selected text

much like we do for Senders and Implementors?
