Yep, return key work perfectly, that close the trade window, and everything that can be closed :), like the inventory.
But my return key are config as a "Confirm" key, that can close but not confirm.
Delete dosen't seen to do anything.
Maybe i mess up somes keys with the key config x')
Actualy i have :
X for Select
Q for Increase amount
S for Decrease amount
Backspace to Go back.
