We have made a basic default key guide for Wings Over The Reich. It's kept on our Support page www.overflandersfields.com/wotr_website//index_htm_files/WOTR-KEYGUIDE.pdf
Note you can rebind your keys and controllers in the Workshop. - "Re Map Keys/Controllers" button will launch the easy to use WOTR Function Binding Tool.
If you want to rebind a key it will check if it's in use, and if so will optionally take you to current binding where you can delete or change it.
Also, check the WOTR FAQ document on our www.overflandersfields.com/wotr_website/support.htm
for help on binding Controllers, and there are stickies and other threads in the WOTR FAQ and technical sub forums
