JP1 Remotes

Roku has secret menus...
https://www.wikihow.com/Roku-Secret-Menu
One of them is a remote Key Press test, which shows the identity of any key you press for all 128 OBCs, 0-127.
(It should work for the Dynex keys, too, but I have not bothered to try them.)

Warning: OBC 5, "EnablePairing" will crash the Key Test. You have to remove the remote's batteries to clear it.

Based on my findings, I added a complete Roku TV Master upgrade at https://github.com/hifiremote/deviceupg ... lete).rmdu
I added all official function names to this upgrade.
The functions given in brackets have shown no obvious effect (so far).

The color buttons are

• OBC 17, Red;
• OBC 18, Green;
• OBC 19, Yellow &
• OBC 20, Blue.

I have not found an app that offers color-based choices, but YouTube acknowledges each of them by bringing up video details.

OBC 29 which acts as a second HOME function reads as "Partner61," meaning it was or will be an App shortcut. (It is the only "Partner" key that does not include an app "name.")
OBC 3 is the official HOME function.

On the Remote Test page, there is a "scoreboard" counting how many times a particular key or type of key was pressed. Three of them (JOIN, A & B) were never acknowledged in all of the 128 OBCs. I suspect that they are three of the four "inactive" keys when they are activated. Roku's online documentation for developers says that a distinct PAUSE key can be activated, too, but is inactive by default. I suspect that is the fourth inactive key. The PLAY/PAUSE key only shows up as PLAY.

The "*" key, which I call the OPTIONS key, is officially known as the INFO key.

The code sequence for the Platform Menu (which contains the Key Test) is no longer working for me. Other secret menus seem to be working fine.

It turns out they changed the entry sequence to
HOME x5, FFWD, DOWN, REW, DOWN, FFWD.
