Skip to 2:40 for the Macro 2.0 binding feature :)
The Ducky One 3 has bad instructions so here's a video on how to change a few common features up on it and bind multimedia keys.
The big missing aspect for this keyboard is the feedback after you've entered Macro Recording mode by hitting Fn + Alt + Tab for 3 seconds - all that illuminates from there is the Fn key, but the Caps Lock key should be blinking slowly.
WARNING: This video may potentially trigger seizures for people with photosensitive epilepsy. Only at 2:00 and 2:54 does the flashing occur, so you may want to skip forward a few seconds at both those spots!

The keyboard in this video is the Cherry MX Red style, but you can find all versions of it for sale here:
