Tip of the day: CTRL + R, CTRL + T

This is the shortcut of the action "Test.DebugTestsInCurrentContext", so you can immediately run the test that has the current focus.

This saves a lot of time comparing to the scenario where you need to locate the test in the Test View and have to select the "run/debug selected test" option.

(I'm not aware of an easier way to achieve this...)

the shortcut is easy to remember because it's short for Run Test! :)
