That was my exact same thoughts.

I would like to have that too. When I looked (oh god its already a year ago) couldn’t find any. I’ve created a control scheme that I would like to share and its fairly complex. Having a standardized files to edit for sharing, or better yet, convert directly from Steam and export to an image (.png or .svg) would be great.

Anyway, no solution, just expressing my interest. I actually want to write a manual for the control scheme.
