Topped, or active, windows can be recognized by a title bar that is not dimmed out,
and black name.
The illustration above shows the active, non-floating Arrange window
The main distinguishing characteristic of this window is that key commands only affect
this window, and not any of the others. The Windows > Next Window menu function
brings the next open window to the top, if it is fully obscured by other windows.
In background windows, you can not only observe changes, but make almost any kind
of change, without having to bring the window into the foreground. To do so, simply
long click on it. Background windows are identified by a white title bar(they can be
positioned next to the top window, or tiled underneath it) and faded name. You can
bring a window to the foreground by clicking on it, clicking on the title bar, or by
accessing one of the local menu functions.
