You can hide the Roblox chat box in-game by pressing the / key, which focuses chat and can collapse the visible chat panel in many cases. If you’re a developer and want to disable the default chat or control how chat behaves, that’s usually done through Roblox’s chat settings or by turning off the chat CoreGui rather than by changing a player keybind.

What to do

  • For players: press / to hide or minimize the chat box.
  • For game developers: disable the default chat UI in your game settings or via the chat UI/CoreGui approach instead of trying to remap the built-in chat key.
  • If you want a custom keybind: you can script your own chat focus behavior in your game, but that does not change the system default chat key for normal players.

Important note

There isn’t a standard way for regular Roblox players to permanently remove or remap the built-in chat keybind. A lot of the confusion online comes from mixing up hiding the chat box, disabling chat in a game you own, and creating a custom chat system.

Example

If your goal is just a cleaner screen while playing, press / once to bring up chat, then it should no longer sit open as a large box on-screen in many Roblox experiences.

TL;DR: Regular players can hide the chat box with / , but changing or removing the default chat keybind generally requires game development control, not a normal player setting.
