Just installed 448 beta over 2.5.2.
had problems with Ctrl-Left Ctrl-Right not working in the editor, (do nothing).
Reset resharper shortcuts. Still nothing.
Went in and assigned Resharper.MoveLeft and Resharper.MoveRight to Ctrl-Left and Ctrl-Right. Still nothing.
Is there something I'm missing to trying to get the functionality back to quick move left and right in the text editor?
