The text in ALL CAPS or all lowercase.

{upper:text}
{lower:text}

Platforms: Twitch and Kick.

Examples

!shout  →  {upper:{args}}
!so     →  Check out twitch.tv/{lower:{touser}} 💜

{lower:} is the one you want when a viewer-typed name goes into a URL: Twitch logins are lowercase, display names aren’t.
