This might just be something I missed (hope it's not a duplicate thread), is there a way to buy an item back from the shop at the value you just sold it for? In my case I didn't accidentally do anything, but I noticed when selling a surplus "Adept's Healing Mail" for 2g that it would cost me 25g (full retail!) to buy it back. Obviously the shop owner has to make a living, and I don't want to ruin the owner's livelihood, but I can imagine an accidental nudge whilst ctrl+clicking causing some upset if had a rare/expensive item to lose. I wouldn't expect the buyback option to persist between shop visits.
At the moment there's no Ooops. I never use Ctrl-Click for that very reason, I always drag / drop as it gives me a moments pause before I complete the action.
Yeah, I actually do the same but more because I enjoy interacting with the loot (your reason is much more sensible) =D
