One of the bigger things I see as a complaint about the Surface Pro 3 (SP3) is that by default the Function keys are not the primary button press. Instead the defaults are the shortcut keys. Additionally, it’s not really documented anywhere how to switch what is primary.
Well, you can. Just use CAPS + Fn to switch between what you want to be primary.
Unfortunately, I use a lot of the Fn keys, but also Home and End. Oh well, guess I can’t have my cake and eat it too.
