The Combine operation will combine a source and action image based on the lightness and darkness of the source image. If the operation is set to Lighter, then all portions of the action image which are darker then the source image will be replaced with the source image. A Darker setting will result in only those areas in the action image that are lighter than the same regions in the source image being replaced with the source image.
Operator dialog controls that have a Trend button next to them offer animation functionality. Trend allows you to set that variable over a set of frames. Each frame of the animation can be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. Variables that have multiple states can be set to any of a number of values in the trend. Variables that are either on or off can only have an on or off value in the trend. You will notice that the trend graphs have equidistantly spaced vertical lines. Each of these lines represents a frame in the animation. The number of frames can be altered using Sequence controls... in the TimeLine pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames.

This control will alter how the Combine operation works. A Lighter setting will result in the action image having areas darker than the same areas in the source image being replaced by the source image. The opposite is true for the Darker setting.
