Recent Acer laptops produce key events when the Hold button on the media control panel is activated and deactivated. These events are relevant for software that wishes to interact with the media panel beyond just using the media control keys. There's also a volume notification key event that replaces the usual volume-up/down events when the panel is in software-controlled mode. Software can react to this to detect volume level changes instead of polling.
