You can just make text bold or italics yourself of course. And adding a hyperlink can be done manually as well. But I agree that buttons would be easier.

And before you ask:

To make text bold add ** before and after the text)

To make text italics add * before and after the text)

To add a hyperlink put the text between [] and immediately add the hyperlink after it between ()
