The computer, an Acer laptop, is entirely up to date (20H2) even the optional cumulative update thatis not yet mandatory as well as the recent update to Edge. The computer has an Fn key used with some of the keys at the top including the F keys togeter with Del Home End etc. there is no Fn function attached to F1, F2, F10 and F11
The Fn key does what it is supposed to do when used with a key that has a secondary function, this function is also indicated on the key in question.
