unwanted format symbols on Outlook 2003 send screens

I accidentally touched a key or keys while typing an email message, when
suddenly everything I type (including my preset signature) shows little
symbols & dots - ie. paragraph symbol & backwards "L") after every word or
line. How do I turn that setting off? I've tried every menu that I know of.
Warning: I'm not very computer savy in the first place. I know the
basics... Please help!!!
