Agreed. Not sure if its possible for the UI to understand or receive contextual information from the device similar to game controllers on consoles (and hey, some consoles have web browsers too, eh?), where you can either tap or hold a button to perform different actions. For desktop and mobile, an analogy might be to left click or tap a control for a set/default behavior, or right click or long press a control for a drop-down menu of choices.
