One of your competitors has a nice feature where, instead of having a
different keystroke for every refactoring, they have a "Refactor this"
keypress, which brings up a pop-up menu of all the valid refactorings
available at the current cursor location (or with the current selection).
I think this would be quite useful, and intiutive for people to learn and
use. I don't think it should replace existing mechanisms in Resharper, but
I think it would make a nice addition.
