How do I delete fonts from font menu above line?

on my font menu, I have 4 fonts that I have used in the past above the line of alphabetical fonts. I only want to use one going forward. How do I remove the others from the used fonts above the line so there is just the sole font I want to use?

this is in the Mac version

I would like to delete, for instance, Amiri.

Work with CellStyles instead direct-Formatting
