We all know that, with Resharper installed, you can run all tests in your solution by typing ALT+R, U, N *.
You can run a single test by placing the cursor in the test method and pressing ALT+R, U, R.
How about running all the tests in the current test fixture class? Well, you can either place the cursor somewhere in the test fixture class (not in a test method) and do the RUR shortcut or, If you're a keyboard shortcut freak like I am, you can do the following:
CTRL+HOME, ALT+DOWN, ALT+R,U,R
Keyboard: 1
Mouse: 0
* You must remove the silly Visual Studio "Refactor" menu first. Right-click the menu bar, choose Customize, then drag the Refactor menu off the toolbar.
