i don't know a lot about the computer but willing to share what little
i do know. i am not sure of the correct computer lingo terminology.
under the word 'message' there are blocks and squares. some you click "on

you can change the font, size, color when typing;
(this is what i usually do) type everything, then go back, highlight the words, and do the changes.
