Exporting a WASD game to Android - control options?

What are my options for player controls when exporting my WASD+mouse first-person shooter to Android?

Also, is it possible to connect a bluetooth keyboard to my Android device, and use that as I would on a PC with my Unity project that’s been exported to Android?

Thanks.

Have you tried the input.getkey ("horizontal:) & input.getkey ("vertical")? Also look through the documentation for mobiles. They have a special API to detect touches and strokes
