I could see myself using this in Lightroom where most features can be triggered by a keyboard shortcut but then manipulated (i.e. dragging sliders) with the mouse. It would be faster to have one hand on a full keyboard and the other on my mouse, rather than moving my mouse hand back and forth or using the mouse to invoke all the features.
