A Suggestion:

Given myself like some other players have to make drastic changes to Keyboard key bindings simply as WASD based schemes are NOT fit for purpose, it requires wholesale remapping for right-handed keyboard use, so it would be handy IF there was a “printout” method that would combine assigned keys with their functions overlaid/referencing a pictographic keyboard representation.

e.g. combining an .eps or other vector graphic keyboard representation with bindings overlaid that is then output to printer producing a good quality print.

This could also be expanded to other common controller types in use or could be split in to principle function (infantry and constant core function like GPS, Map, etc/ground vehicle including boats (Driver function)/aircraft & helicopter (pilot function)
