After Effects and Blending Modes
If you have used After Effects very extensively then I am sure you have put the various blending modes to good use. The one thing that has always been a real pain is trying to test out the different modes and see how each one has an effect. You can quickly cycle through all the blending modes for a selected layer, making it easy to experiment with the results that each mode has on the layer.
To cycle through a layer's blending modes:
1.Select a layer in the Timeline window.
2.Do one of the following:
-Hold down Shift and press the plus key (+) to cycle forward through each blending mode.
-Hold down Shift and press the underscore key (_) to cycle backward through each blending mode.
This is so much easier than having to click through and manually cycle each mode and it also will save you a lot of time trying to decide which mode will work best.
