Moin :) (northern German equivalent for: "Hi!")
Is there a chance to select a whole column with clicking its header?

@teadrinker - yep! :mrgreen: erm, bear with me if it's kinda obvious but,...
a) allows this as well to extract that selection for further processing? :shifty:
b) how to 'unselect' that selection if needed (ie if a row is clicked afterward, the column is still selected)?

If you're OK with it I'd transfer a copy of that code on your behalf to the forum "Scripts&Funtions"-section?!? 8-)

Is it possible to select more than one column while holding down the ctrl key?

With some effort, I managed to apply the @just me's LV_Colors class to get a more contrasty selection:
So cool! :mrgreen: (well, I can't test/use it ATM bc iOS doesn’t support AHK :cry:) Thx a lot anyway 8-)
