 type: text/vnd.tiddlywiki
 
-The `tm-fold-all-tiddlers` message folds all tiddlers in the current story list. It does so by setting the text of a state tiddler to either "<<.value "show">>" or "<<.value "hide">>", according to the fold state.
+The `tm-fold-all-tiddlers` message folds all tiddlers in the current story list.
+
+Internally, it sets the text of all of the state tiddlers corresponding to tiddlers in the story river to "<<.value "hide">>". The state tiddler titles are formed by prefixing the tiddler title with a prefix that defaults to `$:/state/folded/`.
