I've read the manual twice, and watched programming guide videos on youtube, but while I can program hotkey 1-6 just fine, I can't find how to actually trigger them.
I found how to trigger the "Fun key+N" keys, also mentioned in the manual. The green key appears to have the name "Func", even though I can't find that actually in any manual. You long press the green key, and then can trigger 0-9, and * and #.
But what about the "Hotkeys"? How do I trigger them?
