Cool Extension: Vim Emulation
Jared just released a cool new editor extension for Visual Studio 2010 Beta 1 to provide Vim editor emulations. You can find this on the VS Gallery and through the Extension Manager in VS 2010, so go test drive it today.
He also talks more about what this extension currently supports and where he's going with it on his blog. And, sounds like he plans to also release the source code for it as well some time soon...
