I just discovered, after months of RubyMine use, that the GoTo functions work like fuzzyfinder in Textmate. There are a lot of useful shortcuts under the GoTo menu; the ones I am finding most useful are Ctrl+Shft+N for finding and opening a file, Ctrl+N for a class, and Alt+Shft+N for jumping to a corresponding Rails object. For instance, if I am in the People controller, I can jump to the Person model, People views, etc, bringing me that much closer to fulfilling my dream of never having to leave the keyboard when developing.
