These interface features are standard in Stylus RMX:
Down Arrows Open Option Menus
Whenever you see a single downward facing arrow, this means that you can click directly on the window to reveal a drop-down option menu specific to that function.
Up / Down Steppers
These UP / DOWN arrows let you move incrementally through a list of options.
In the picture above, you can use these arrows to step through the different available LFO waveforms.
Viewing a Parameter Value
You can view a current parameter value by clicking on the parameter and not moving it. The value appears in the Value Display in the Footer.
