Some MacBook models have issues with the F3 commands.

I have a MacBook Air 15-inch, M4, 2025 and some F3 commands like F3+H for tooltips don’t work. also, f3+Q opens the notes app instead, which is probably something on apple’s end. I also couldn’t use f3+h on my previous MacBook, which I forgot what model it was. It might be a Mac exclusive issue, though, so I don’t know
