So you mean it would have no effect, yes? On restart it will have the same settings and firmware it did prior to pressing the reset button?

I looked at the QMK docs to see about using it from the terminal. But I am not clear about how to get around the issue of the firmware not being up to date.

I don’t quite trust various bits and pieces I’ve found about how to use it around the web. Like the configurator page for this device says

Reset Key: Hold down the key located at K00, commonly programmed as Esc while plugging in the keyboard.

compared to the keychron docs I linked to in the OP which says

reset the keyboard by pressing fn + J + Z (for 4 seconds)

And also describes an actual reset button located under the space bar.

Why are they different…? It seems like keychron probab knows how to reset their own device. So I wonder if it is a good idea to load anything from this qmk page using methods I don’t understand well because I’d never be able to get myself out of a mess.

I have a form like this I do regularly for work. I actually fax the form, I don’t even send it electronically. But I like to fill it electronically so I have my records on the computer. Because it is 2023. I had to use my home computer (linux) to generate a copy of the form, then use a floss editor I managed to get working on windows work computer to annotate on top of the form fields. For some reason it’s really hard to get the annotations to line up with the form fields. So sometimes I have to correct it by hand after printing to clarify.

It is a zero security form, there is no need to have all this rigamarole. The form is freely available on the internet and anyone with a fucking fax machine could fill it in and send it on behalf of anyone else. Fax machine is the biggest hurdle; who the hell has one of those.
