Hi amoun!
Thank for the warm welcome!
No, I don’t need to use the key only for F10 by itself, and when I need to I’m fine with pressing [fn].
I’d ideally like to remap it to some other shortcut (yet to determine what I want that key to do), or disable the ‘Flight Mode/Airplane Mode’ toggle entirely if possible - I’ve found my muscle memory keeps hitting that key wrongly as my old laptop had a different function bound there!
