Closing a Window
To close a debugging information window, click the Close button in the upper-right corner of the window.
If you want to close the active window, you can also click Close Current Window on the File menu or press CTRL+F4.
You can close one of the debugging information windows by pressing ALT+SHIFT+number, where ALT+number are the shortcut keys that open this window. (For a list of the possible shortcut keys, see Opening a Window.)
To close all Source windows at the same time, click Close All Source Windows on the Window menu. This command will not close a Source window that has been designated as a tab-dock target. For more information on this setting, see the Source Window topic.
