[2023] Steam deck help

I am new to this game, and the genre. I just played grim dawn, and Diablo 4. I tried path of exile, but that was too complicated. I play only on steam deck, and decided to try this game. So far, it’s great in the graphics. I am only about 40 mins into the game. The only complaint is the steam deck/game pad controls are not that intuitive. They are a bit clunky. My biggest complaint is selling the items. I have to grab 1 by 1 and drag over. It’s very slow and time consuming. Is there a faster way to go it? Is there any bindings or anything you can give me to make life easier? Thank you!
