That's a console window`, and you open it with AllocConsole. See all of the Console Functions at MSDN.
回答2:
Default key mapping is Ctrl + W,O
Or do View menu -> Output window
There is also an immediate window which let's you execute statements, like ?myVal and it will tell you the value. It can be found at Ctrl+D,I or Debug->Windows->Immediate
