[Question]: Multiple Select for actions like var_listWit[@n=textWitnesses]

[Kolophonium0]

In actions like mentioned above there is the option to have a multiple select. I tried it and it works kinda. When I click on a value and then hold shift and select another it then selects all the values between, including the two selected values. I don't think, that is the intended way this should work.
Is there a way to only select the values I want, without the need for them to be consecutive?

Did you tried [Strg] instead of Shift? That's usually the way to select different entries (also in other software if I remember correctly).
