A window manager controls how windows appear and behave. The window manager manages where your windows are located, and which window has focus. The window frame contains buttons that enable you to perform standard actions such as moving, closing, and resizing windows.
You can set some window manager preferences in the Window
Behavior
preference tool. This manual describes the functions
that are associated with the default configuration of the Metacity
window manager. The default configuration is specified in the Window Behavior
preference tool.
