The F1-F12 function keys on my Mac changed all of a sudden. They all started doing different things. I tried to go into keyboard preferences and managed to restore F1 and F2, but there are no other options to change the rest. Does anyone know how to do this?

To find out if it's system wide or user specific, try this...
Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
Does it work in the new account?
Then I suspect something amiss with the install of the OS, or some 3rd party SW interfering.

There is also Malwarebytes…
So, is this what you tried?
Yes, please get both of those & post the output of Etrecheck.
I’m really not too sure what happened. I was typing something on the keyboard and all of a sudden this text box popped up on the right and it had all this coding stuff and html <> texts (I have zero insight into this area 😂). Then after I managed to get that to disappear, all the functions went weird. But when I managed to open that box again, there weren’t any options to change those kinds of things.
What OS are you running?
High Sierra 😊
I already tried that. No response.
It was exactly the same on the new profile
These links will obviously help me to do what you say you think I should do? Haha. Sorry, I just have no clue. Really do appreciate the help! I’ve attached a photos of the text box thingy
