WOW! - Eric, you rock. --- The only thing I had understood was the mimicing with hex code \x22 or single-quotes. Unfortunately single- quotes are used by the plugin as start- and end-terminators for the whole sequence. Your approach of "compound macros" sounds very interesting, but I am not sure that I get the clue. Am I correct, you use tiddler sections as a kind of slicing? Michael
