How do you talk in Roblox?

First of all you have to be on ordinary safe chat (if you are on super safe chat you can only use a list) if you are on super safe chat i'm not exactly sure how to switch it back but if it helps...if your on ordinary safe chat simply press the "/" key and start typing. when your finished just press enter and! voila! there it is on the top left corner! example: /hi how are you? "enter" ironhuntsman: hi how are you? ( in top left hand corner)
