Here's the background of me asking. As there is no discernible "this macro doesn't even exist" notification, how am I to know if an empty tw5 even has a "wikitext-example" macro ...or where to find it if I were to search for it in
tw.com? ...which gives me all the codebits where it's used, rather than defined or documented :)
Which brings me to thinking that maybe a "keywords" or "sticky" field may be highly useful to indicate will make tiddlers more prominent in the search results when the search term is contained in the
field value of this tiddler, e.g. the "keywords" field for the tiddlers defining or documenting the "wikitext-example" macro would contain "wikitext-example".
