Steps:
1. Launch photoshop ;-) 2. Create 3-4 layers with something on them in various colors , like some strokes with paintbrush (the colors need to overlap themselves so we can see the blending mode changes) 3. click the blending mode dropdown with mouse, and start using arrow keys (up,down) to change the modes - nothing will happen at all. If you change the modes with mouse it will work correctly.
