Sadly the changes needed cannot be fixed with a simple key remap
You press "F" to open barrels.
You have to reach for "Escape" to close barrels.
You press "R" to talk to merchants.
You have to press "Enter" to choose from merchant's menu's
I suggest that you at least look into fixing you inconsistency in controls for the game.
If you need help here are some possible fixes:
Since you open barrels with "F" why not make that the standard OK button. this would mean "F to open barrels, "F" to talk to NPC's and "F" to select from the NPC menu's.
A secondary interact button is just annoying.
And when you open a barrel i would think you just ported the "LB"/"RB" functionality directly to the pc to switch between the inventory's. but in thoose menu's you are not using "A" and "D" so moving "LB"/"RB"to "A"/"D" would leave "Q" open to be used for closing the different menu's like barrels.
And you would not have to move your entire hand away from the primary controls when resuppying.
This would make your new UI changes playable even on PC.
