As fast as you can type, Visual Studio searches your entire solution for a file or path that starts with the characters you type and you can quickly select that file (with the keyboard using the arrow keys if you wish) and open it.

For those of you unfamiliar with the Command Window, you can think of it like an Immediate Window that you use with the debugger, except that instead of controlling the debuggee, you’re controlling Visual Studio. It’s like the VS macro editor, except that everything you type takes immediate effect. To have this conveniently just a Ctrl+/, > keystroke away, especially when “>of ” (short for Open File) is such a convenient acronym to search across your entire solution is awesome.”
