Open file the fastest way in VS: >of

Say i have a huge VS solution with quite a lot files which might exist under a lot of directories. and i want to open this one file.

How do you usually do it? Go to File->Open->File the directory and click open; Or navigate to the right directory on the solution explorer, and double click on the file? What if you don't remember which directory it is under? 

VS has this FindInFiles icon and input text box right next to AnyCPU combo box.  Start typing in >of in that Find In Files icon, it will do a file name mapping and auto complete the file name for you. Once you got the filename right, click Enter, your file is opened.

 It is very fast!
