We’ve blogged about this feature before (searching for things by name, including types, files, methods within a file and more). Scott Cate has listed it as his favorite feature of the day in his blog post ReSharper: Don’t develop without it.
Hope you’re enjoying Ctrl+Shift+N, Scott (and all other users, too)
P.S. On the topic of ReSharper’s price tag, please be aware that we offer Personal Licences to individual ReSharper users. You can save $100!
