+type: text/vnd.tiddlywiki
+
+The ''get'' filter operator replaces the titles of the tiddlers in the current list with the values of the field specified by the operand.
+
+For example:
+
+|!Filter String |!Description |
+|`[all[current]get[draft.of]]` |If the current tiddler is a draft, returns the original tiddler, otherwise returns an empty list |
