I have learned that when pressing [Alt] and [NumPad2] then [NumPad1], you can type the § symbol to use for formatting words within a certain range of numbers and letters, despite having had known this for a while.

It has come to my attention that this cannot be done for me, for some unusual reason.

Is there a possible solution to this that I could make this work once more?

I'm wondering this in 1.16.3 and 1.16.4
