When a tool window is not docked...
Note: Using the Move command from this menu will prevent the docking targets from appearing. If you want docking targets, use the tip documented here. This is the same as doing a Ctrl-Drag using the mouse. Also, if you press Alt+Spacebar, you’ll get the main Visual Studio window system menu, hence why you must release the alt key before you press the spacebar.
