"Whether this device dispatches touch events for movement."

It isn't just for movement, it's just whether the devices dispatches touch
events, isn't it?

"This is used to detect mouse events which represent only an action..."
Maybe "This lets developers avoid handling both touch and mouse events
dispatched for a single user action"
