As TonyM indicates, yes, if you provide what the information that "google.com" should be associated with "Google". This association could for example be made in a dictionary tiddler.
Another approach would be to mechanically extract the string segment of an url that appears between www. and the succeeding forward slash, etc. E.g from https://www.google.com/foo... you'd extract "google" (..and then perhaps convert it into "Google"). That's doable and not overly complicated. <:-) > -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
