In Visual Studio you can press SHIFT+ALT+C to create new class file. I am looking for similar shortcut for new interface file and new "basic unit test" file. I have Telerik JustCode so please do not suggest simillar product. But if a small extension exists for example, it would be nice to know. BTW I am using Visual Studio 2010 (C#).
There are no built-in solutions for this, but you can easily record macros (In the Tools menu):
You can rename them in the Macro Explorer (Alt+F8)
You can then assign shortcuts to those macros in Tools → Options → Keyboard.
EDIT This doesn't work for adding a new Basic Unit Test. You'll only get to the New Test selection dialog, even with this method.
