Bold font option

I'd love for there to be a option to have bold font. Sometimes I need to put an emphasis on something so that I don't get misunderstood but putting it in all caps makes it look rude or louder than I intend. If not a bold font maybe but a slanted font, or an underline option. Or maybe all three. Idk lol however you guys can/want to do it is fine I'm just think having that ability will emlimate so many misunderstandings.
