As far as I could see, there is no way to map buttons for the Take All and Exit actions in the container/box/corpse screens using the in-game options menu. And the buttons E and A for Take All and Exit are rather uncomfortable for my regular choice of buttons. Is there any way to map buttons for these actions via editing some game configuration file?

So, there is no way?

I would like to know this too, but I don`t think there is.

I'm not sure I follow. Aren't you able to go to the options menu and map the keys as you wish? I have "take all" on my A key, and E for Exit. A is still my "Strafe Left" key, but it doesn't matter when in inventory mode while in containers. Works great.

Edit: Oh, you probably don't use the wasd keys for movement, I take it. This game is what broke me of not using them, hehehe. Sorry.
