Float Windows
Float windows are so named because they always “float” in the foreground, even above
the topped normal window (if there are a lot of open float windows, they will
inevitably cover each other up—just click on one to bring it to the foreground).
The illustration above shows the Arrange window as float window.
Float windows are recognizable by their narrower, gray title bar. Mouse operations can
be carried out in the same way as in normal windows.
The most common example of a float window is the Transport window. You can open
any other window as a float window by holding down Option while selecting the
desired edit window from the Windows menu.
Note: Holding down Option while opening a window with a key command does not
open the window as a float.
Relationships Between Windows
The two buttons at the top left of a window, determine its relationship to the song
position (Catch), or to other windows (Link, Contents Link, or Contents Catch).
Catch
The Catch function ensures that the visible section of a window follows the song
position as the song plays.
