Desktops and Laptops have different startup hotkey mappings in order to access the BIOS, recovery manager, and other settings.
Its frustrating having to guess and reboot in order to find which keys work… it also doesn’t allow for the full range of options to be found as some machines even require a combination of hotkeys to be pressed…
Is there a location/config file that we can access with powershell that shows the key mappings and what options are available.
For example
Macbook pro SHIFT key = safe mode Fn key + F8 key = Recovery Manager Alt key = startup Manager Alt + Cmd + P + R = Reset NVRAM or PRAM
Since those key bindings are vendor / hardware specific and built in the BIOS - not in the OS I would not expect PowerShell to be able to read those config options in any way.
So the answer to your question, if that was a question is: “No, unfortunately not”. Sorry.
