When you give a Cue a bump behavior, it activates when you hold the Bump action button and is active for only as long as you hold your finger on that Bump button. When you release the bump button it releases the cue. Useful for when you want to do a quick and dirty flash effect of a light or a group of lights (because you can also tap the bump button repeatedly quickly to go the values/colors saved into the Bump Cue). Bump cues are also useful when you want to have a light or a group of lights flicker to black. First you record the group of lights on at the intensity and color you want the look of your scene to be to a Cue, then you clear the stage and Go that Cue (Lets call it "Creepy Look"). Then you select the light(s) that you want to flicker and set them to 0% on your stage; record those to a Bump Cue, and clear the stage. Now you can tap or hold the Bump cue to "0% bump" or quickly black out those light(s) for as long as you hold or tap that bump cue. A second cue should layer over the first cue that is active.
