sillygrapist: Found somewhat a solution for the problem. There is this freeware program
http://www.autohotkey.com/download/ which allows you to rebind every key by using very simple scripts.
Thankyou, thankyou, thankyou! I've been struggling with the key bindings for The Witcher 2 for three days now, binding and rebinding via the .ini files. I almost got it to my liking, even remapping the "Quicksave" to F12, which is my quicksave key for all games. But Spacebar (hardcoded as the "Take All" key for loot) remapping was off limits to me and would not remap at all. Until now that is!
Thanks to your post about the Autohotkey program I can now use End for "Take All" and have mapped the mouse scroll up/down for things as well. So much better!
So thankyou very much for your very helpful post,
sillygrapist.
