@Joshua: Thank you for your answer. I had tries with <$macrocall> but it was not the gotcha. What I had wrong was really, in retrospect, the art of puting [, ( and < right within my filters. I am still dumbfounded by what the way-that-works vs the way-that-I-would-thought-would-work.
I'm now looking at the subfilter filter. It seems to be the map operator I was asking for. But here again, I have two problems: 1) writing my filter and 2) using subfilter! But those problems do not belong to this thread. Regards, Le lundi 21 septembre 2020 à 01:52:12 UTC+2, [email protected] a écrit : > Hi, > > I know that TW syntax can be overwhelming.
