Framework/Linux Newb here, please be kind!
As there isn’t a hardware manual for the laptop, and I am new to the Windows/Linux keyboard (many decades Mac only), I thought the F12 ‘gear’ icon was to open the System Settings, but turns out to launch Rhythmbox App.
When searching here I found a 2024 Topic that pointed out that is the Framework logo 
and sometimes/used to launch the Framework site.
I also tried the F9 ‘display’ key and nothing happened, so not sure what it is. Maybe to switch displays when there are multiples. With only the laptop it doesn’t do anything.
Also my hands are used to the Mac keyboard, which has controls located differently on the Function row. Is there a fairly easy way to remap/reassign them? I am gradually getting used to the control locations but some of the keys I don’t use at all and would be interested in changing them if it’s not too tricky.
On the Mac I found a Terminal command couple of years ago when the keyboard backlighting keys were changed to some voice thing and do not disturb, neither of which I used so was able to remap them back.
Or should I ask this on the Ubuntu community?
