JP1 Remotes

I have a 2015 Sony X850C. I've started using Bravia Sync for the first time to control a TiVo Evo Force 1.
There are a couple Action Menu/Sync Menu options that take several clicks to activate, but I can't find button codes for them.

I don't know if they exist, but I'd like codes for:
Home (Menu) - The device I'm controlling, not the TV itself. It does the same thing as the TiVo Icon Menu button.
Power Off - Again, the device, not the TV. Puts the box in standby. Something there seems to be no other way to do.

For anyone else who's curious how the TV can control another device, it turns out that "Bravia Sync" is Sony's brand name for HDMI CEC (Consumer Electronics Control), a feature that lets you control multiple connected A/V devices (like Blu-ray players, soundbars, AV receivers) with a single remote, typically your TV remote.

As for any missing button codes, best I can suggest is that you download all of the Sony Bravia TV upgrades that we have and compile a "best of" code set:

These are all the Bravia Sync commands from my Sony remote:
They're in this upgrade of mine:
