TV remote style are a bit cumbersome. Same with the "5 way" DPad style directional.
People who only go forward might get away with a single button "selfie" clickers.
The buttons must have a light touch.

Also, if you are persnickety as I am you will want to defeat the Onyx long press detection.
With the Onyx mapping of short/long it has to wait until you release the button to do anything.
This applies even for keyboards. If you use a USB or BT keyboard look closely how it reacts to the PgDn button.
It doesn't do anything until you release the button.
This is in contrast to letter keys which type a letter when you depress it.
