The Channels dialog, like the Layers dialog, has a hidden menu that
can be displayed by right-clicking in the title area
of the Channels Palette. This menu is shown in
Figure

As shown by the red arrows, many of the operations available in the
Channels menu are directly accessible from the button bar. Most of
the functions in the menu are organizational:
New Channel,
Raise Channel,
Lower Channel,
Duplicate Channel, and
Delete Channel are all self-explanatory. Of particular importance is
the
Channel to Selection function, which is the inverse of the
Save to Channel
function.
Channel to Selection creates a
selection in the image window corresponding to the active mask in the
Channels dialog.
The remaining functions in the Channels menu, Add to
Selection, Subtract From
Selection, and Intersect
With Selection are described
in the following section.
