Mario, to see what I mean about examples, open the TW wiki and search for .oper. You will get 24 retrieved. All the examples use this format.
I can't remember other examples I found....I have 'found' many things and most of them have now been 'lost' :-) bobj On Thursday, 1 October 2020 at 04:13:10 UTC+10 Cade Roux wrote: > I sympathize. > > It's very hard for me to switch gears into TiddlyWiki filter and widget > syntax.
