      * #{GMSTName}: retrieves String value of the GMST called GMSTName
+     * #{setting=CATEGORY_NAME,SETTING_NAME}: retrieves String value of SETTING_NAME under category CATEGORY_NAME from settings.cfg
      * #{sCell=CellID}: retrieves translated name of the given CellID (used only by some Morrowind localisations, in others cell ID is == cell name)
      * #{fontcolour=FontColourName}: retrieves the value of the fallback setting "FontColor_color_<FontColourName>" from openmw.cfg,
      *                              in the format "r g b a", float values in range 0-1. Useful for "Colour" and "TextColour" properties in skins.
