Typing / in an empty message box will display a list of all slash commands. Slash commands have an additional feature, autocomplete, that displays a list of possible commands based on what has been typed in the message box. Slash commands are messages that begin with / and trigger an HTTP request to a web service that can in turn post one or more messages in response.
