I tried messing with input.xml and input.settings and no luck on either. I don't even think they're exposing the movement at all, or at least I haven't been able to find it. I did some quick looking and autohotkey seemed like a good option here. It's free with no attached BS, and it's definitely a well known app so little risk.
To remap keys with AHK is pretty simple. The format is:
e::w
This sets it up so that every time you press E on your keyboard, it presses W instead. I tried it quick and it seems to work fine.
To get it working, just download autohotkey (
https://www.autohotkey.com ), create a file on your desktop called something.ahk, and put something like the following in it:
SetTitleMatchMode, 2
#IfWinActive, The Witcher 3
e::w
s::a
d::s
f::d
w::e
g::f
a::g
#IfWinActive
Save the file, then double-click it to run it. The script knows to only remap the keys while you're in Witcher. If you need to disable it, just right click the taskbar icon with the green H and exit.
It seems to work fine, but I haven't done a lot of testing. Might need tweaking, use at own risk.
