If it's not listed in the guide, then I don't. Galaxy map, System map,
Toggle Rotational Correction, Toggle Orbit Lines, Silent Running,
Jettison All Cargo, etc. are all handled via in game menus (External Panel
for the maps, Internal Panel for the others).
Headlook and related controls are not included since I fly exclusively in VR.
Feel free to change the mappings to suit your use.
Go into the game menu, find the thing you want to map to a button, click the
mapping, press a button on the stick (with or without the pinky button pressed
depending on if you want it on the primary or alternative map).
If you're going to move the 'major' functions (Primary Fire, Secondary Fire,
etc.) map both the un-shifted and shifted button presses to the action do you
don't suddenly lose the ability to do something important while doing something
unimportant.
Maybe. For personal use you can just Photoshop the current ones. If you've got and open source project that you want them for drop me a line and I can sort out the assets for you. If you want to use then commercially, or in a closed source application we'll need to talk.
