Is this a possible or already implemented feature at all? For instance instead of using my mouse to click the up and down arrows when purchasing or selling items, an option somewhere so that I could simply use the arrow keys instead? (Up/Down to change item, left/right to change amount)
Truth be told, I ask this more in concern for ease-of-play in the experimental android version than anything else, although it would be my personal preference when navigating the same screens on my laptop too.
