The Xfce 4 window manager manages the placement of application windows on the screen, provides beautiful window decorations, manages work- spaces or virtual desktops, and natively supports multiscreen mode. It provides its own compositing manager (from the Xorg Composite ex- tension) for true transparency and shadows. The Xfce 4 window manager includes a keyboard shorcuts editor for user specific commands and basic windows manipulations, and it provides a dialog for advanced tweaks.
