{expand:string}

Runs a second AA expansion pass over its argument. Templates normally expand once; a value read from a field is returned as plain text, so any AA constructs stored inside that value are left untouched. Wrap the read in expand and the engine resolves those constructs too. It is the standard way to run template syntax that was stored as content - for example a mail body or message template held in a field. Plain text with no AA syntax passes through unchanged. Note that inline syntax you type directly is already expanded by the normal pass, so expand only adds a visible effect when the text still contains unexpanded constructs after the first pass (typically because it arrived from stored data).
