Apple Logic Pro 9 - Manual (Page 89)

Key focus areas within windows—such as the Arrange window—are indicated by a white
focus frame around the focused area.
To assign key focus to a window or area
Do one of the following:
µ
Choose Window > Cycle Through Windows (or use the corresponding key command).
This command assigns key focus to the next open window, if it is fully obscured by other
windows.
µ
Click the window title bar, or within the working area.
Be careful if using the latter option, as you may accidentally insert an event or region if
the Pencil tool is active in the window.
The Arrange window can incorporate several other windows in different areas. These can
be given key focus by clicking the background or title bar of the window (the area of the
Arrange window you want to use), or by using a tool in the window.
Tip: You can also use Tab or Shift-Tab to cycle through the Arrange window areas: Tab
cycles forward, Shift-Tab cycles backward.
The main characteristic of the key focus window (or area of the Arrange window) is that
key commands only affect this window, and not any of the others.
Working in Floating Windows
Floating windows are so-named because they always float in the foreground, even above
the key focus window. (Opening numerous floating windows inevitably leads to them
covering each other—click the one you want to move to the foreground.)
