As a Roblox developer, it is currently too hard to ensure that Chromebook users will have a good experience playing games because they do not have a hotkey to open the built-in chat.
I believe this speaks on behalf of all ROBLOX developers, but this is an issue that Chromebook users face that could be improved.
Chromebook users are unable to open the chatbox by pressing " / " which is sometimes a bit inconvenient because keep clicking the button for some people is a lot more of a pain to do then simply pressing " / " on their keyboard.
