I have to say, most of the time you give code, like not so easy for beginner to understand, and you give very little explanation if any. Here you give an on text event with a regex if statement and you say "you'll have to escape special characters". OP started by saying he is new to this, I'd say he has no idea what you are talking about.
I'm not saying regex are not a good solution here, but explaning a bit how they work in general etc would be a must here. Perhaps he wants them to be word only or something.
