Escaping period in Visual Studio Find Immediate Window

I learned about entering into the immeidate window >of filename trick in visual studio, but when I enter a period, which is reserved for separating menu items, it populates some junk that is irrelevant to what I want. For example, if I typ开发者_如何学运维e >of web.config, and as soon as I get to the period (4th character) it would populate junk into the box.

Does anyone know how to escape it?

If you want to enter "." without auto-complete being activated hit escape then enter ".", auto-complete will kick back in and you don't have to worry about inadvertently completing the wrong file name.
