Great documentation for the Virtual Railroads DB101, but many keyboard shortcuts are different than most locos, and rather than go through all the text explanation I created a quick and dirty cheat sheet for the command keys. Sidebar: Wish TS/TSW had a way to configure keys to commands (or hotas devices) like flight sim programs. Note: I've found the PZB/AFB implementation to be very good - almost as good as TSW2. I have not had a chance to check out LZB yet.
