LabVIEW
multiple selection in listbox without using ctrl key
Solved!
I recall that there is/was a Windows mouse setting that made it easier to operate with a trackpad by making certain mouse clicks a one-click affair, like dragging and dropping, and selecting multiple things. That may be worth looking into, if only to standardize all your inputs. (However, I don't know if LabVIEW controls would "subscribe" to that setting.)

I guess there should be an event for "long-click" as often used on tablets. Is there an idea for that already?
A while ago I wrote some code that would allow item selection in a listbox, MCLB, or Tree by checking boxes with a single mouse click, or right clicking for select none/all. Here is the included example:
