This is seriously not a thing in any other game I play or are familiar with.
Can we please disable it. I can't remember to press it for just this one game so all it does is act to double all my mouse clicks with needless reminders that I didn't click it again.
I'm not going to. Stop reminding me!
Also, when I'm selling consumables - why ask me how much of each stack to sell? By default I want to sell it all. (ctrl does not serve to sell the whole stack (but, if ctrl to confirm is going to be a thing, perhaps it should bypass this silly dialog too)).
