A window manager controls how windows appear and behave. The window manager manages where your windows are located, which window has focus, and the theme of the frame on the windows. The window frame contains buttons that enable you to perform standard actions such as moving, closing, and resizing windows.
You can configure some window manager settings in the Window Focus
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 Focus
preference tool. This manual also describes the
default functions of the Crux theme.
