You can save a profile of all of the settings on the Keyer tab and apply it to other sessions. You can also use this feature within a given session to preserve a particular set of settings before making changes, and then easily return to them if you don't like the results of the changes. The profile encompasses only the Keyer slider settings; it does not include the mathematical model that's created when you click Set Key or Apply Points.
To create a profile, click the Save button in the lower-left corner of the Keyer tab. A standard Windows Save As dialog box appears. The default path is My Documents\Adobe Ultra CS3\My Settings. The profile's extension is .cks.
To apply an existing profile to the current session, set the key, click the Load button, browse to the correct folder if necessary, and then select the desired profile.
