This is to help left handed players to play Skyrim SE.

How to use:  Download controlmap.txt

Go to your Steam folder\steamapps\common\Skyrim Special Edition\Data\Interface\controls\pc
place controlmap.txt there.
Set the properties of controlmap.txt to "read only" if not already.
Go into Skyrim SE and in game configure your controler settings.
Once done back out and it should save it.
Now in your Skyrim SE folder there should be a ControlMap_Custom.txt file.
This is where it stores your new control configuration I believe since it
 always appeared when I erased it and configured in game again.
You should be able to bind numpad keys now,but some will look like a bunch of 
question marks "???"
idk what can be done about that atm.
This is the best solution I could come up with until 
skse comes out for Skyrim SE and someone can make a real keybind mod for it.

Lefties Unite and Enjoy!
