+%D \stoptyping
+%D
+%D We used it to mark synonyms that should not be corrected by the editor. Sort of the
+%D reverse of not having a word in a vetted wordlist. A bit out of place in a typesetting
+%D system. If really needed we can support multiple words seperataed by spaces but I didn't
+%D need it. And \unknown\ fonts are supported but at fixed size!
