@TiddlyTweeter I open my TiddlyWiki in firefox with a profile that uses the firefox add-on "*Export Tabs URLs*". e.g. this add-on extracts title and url from this web site as follows:
[[Regular Expressions in filters ... VARIANT methods & WEIRDNESS - Google Groups |https://groups.google.com/forum/#!topic/tiddlywiki/l-OSoKg4j4E]] <br/> [image: 25-09-_2019_23-09-09.png] At the red arrow I can reduce the selection with RegExp from the offer of all opened tabs in this firefox profile to usually one URL. And I want as little typing as possible. I want to type as little as possible, but sometimes I need an AND to be able to reduce similar pages to one. To select the third opened tab I have to type "*reg*".
