Power key on Pi 400

Would it be possible to enable the power key on the Pi 400 [Fn-F10] to perform the MoodleBox shutdown? It works great to power on.

Power off by holding down the Fn+F10 keys for two seconds. This carefully shuts down your operating system, so you don’t cause any corruption to your memory card.

Nicolas Thank you; that's very useful.

Great tip! I confirmed this on my Pi 400, having it hooked up to a terminal and watching the linux system do a shutdown! One can confirm the Pi 400 has been shut down completely when the green light goes off. I'm going to guess/hope most Pi 400 users would use that sequence rather than pulling the power supply.

I also used this command (last -Fxn2 shutdown reboot) to see how the last 2 restarts were done. It's a little confusing, but it's another way to check the system if you have console access or ssh.

A graceful shutdown would show up as a reboot line followed by shutdown line, as in the following example:

# last -Fxn2 shutdown reboot
reboot   system boot  4.18.0-80.el8.x8 Mon Aug 31 06:33:11 2020   still running
shutdown system down  4.18.0-80.el8.x8 Mon Aug 31 06:33:01 2020 - Mon Aug 31 06:33:11 2020  (00:00)

Thanks Steven and Dan for the confirmation.

@StevenM: I've edited the shell commands in your post so they are better displayed.
