I recently installed Visual Studio 2013 RC, and then re-installed Resharper 8.01 so that it would be available within VS2013. And it is, i.e., I see all the Resharper menu items. But so far as I can tell, none of the keyboard shortcuts work. For instance, if I press Ctrl-T, it transposes the two characters at the cursor rather than bringing up the "Find classes and files" dialog box.
I've tried going into Resharper, Options, Environment, Keyboard & Menus, and applying the appropriate scheme, but it didn't seem to have any impact. I also uninstalled Resharper 8.01 and then reinstalled it from scratch, to no avail. Keyboard shortcuts work fine in VS2012, but not in VS2013 RC. (On this one machine, at least - they work fine in another machine that I tried.)
