You can also shuffle the window through an option in the root menu. Choosing the Shuffle Up option will place the window at the bottom of the window stack on the top, consequently making it the active window. This can be repeated until the desired window is made active. The Shuffle Down option will place the window that is on top of the window stack and places it on the bottom of the stack. Some windows will also have a menu bar below the title bar.
Menus are a way of selecting commands from a list while using the mouse or keyboard.
To bring up a menu, hold down the button on the menu you wish to display. To select an option, you must continue to hold down the mouse button. As soon as you release the button, the menu is removed from the window. Once a menu is displayed the current option will be highlighted. To select a different option, drag highlight bar to the desired option and then release the mouse button.
