10. 10 MS Visual Studio How to Use & Configure §Managing the variety of windows in the IDE §Usually, you will find it easier to work in the IDE if you either close or auto-hide the windows you are not currently using. §The easiest way to close an open window is to click the Close button on the window’s title bar. In most cases, the View menu provides an appropriate option for opening a closed window (.pdf, page 4).

11. 11 MS Visual Studio How to Use & Configure §Managing the variety of windows in the IDE §Rather than closing a window, you also can auto-hide it. You auto-hide a window using the Auto Hide button (shown earlier in Figures D1 and D2) on the window’s title bar. The Auto Hide button is a toggle button: clicking it once activates it, and clicking it again deactivates it (.pdf, page 4).
