How do you get the typeing bar on roblox?

You can access the chat bar by pushing the '/' key in-game or by simply clicking on the bar at the bottom of the screen. Please note that there will not be a chat bar if you are under 13, not logged in, or if your parents have disabled the chat bar via their parent account. If this is not the case and the bar is still not there, you may have to turn off the "super-safe chat" option in your account settings in order to use the chat bar.
