Finding use is a tool window, like any other, so the shortcut to close it is Shift + Esc (or, if that doesn't work, check what it says in VS Tools | Options... , Keyboard , Window.CloseToolWindow ).
TOLD that I was always a bit foggy how to use the keyboard to get focus to / from the Windows toolbar - Ctrl + Tab works fine from the code window into the Window Tool, but it doesn't always work to pull you out ...
