[@Skwint] Another townie here.

[@RedPandaGamer] if by attachment you mean the thing that hides the character sheet, it's a "hider" - You can type things in between hider tags like [%hider][/hider] (without the percent sign of course) and it will all be within a hider. Also, that icon with the crossed out eye in the same area as the bold, italics, etc. does the same thing!
