Modifier keys are combinations of a keyboard key and a mouse key that are used to generate pop-up menus or to perform interactions. Generally a keyboard key is kept pressed and during this pressing, a mouse key is clicked (e.g. to get a pop-up menu) or kept pressed (e.g. zooming).
A list of available modifier keys with conditions and actions:
