-- **dpad_hotkeys:** dpad works as hotkeys without holding Start button
-- **switch_potions_and_clicks:** L1/R1 works as left/right mouse clicks by default, and as health/mana potion while holding Select
-- **sdl2_controller_mapping:** allows you to remap controls. It uses https://github.com/gabomdq/SDL_GameControllerDB syntax
-- **enable_second_touchscreen:** enable/disable back touch mapping to L2/R2
+- **Mapping:** allows you to somewhat remap controls. It uses https://github.com/gabomdq/SDL_GameControllerDB syntax. Deprecated, use padmapper menu in-game if you can.
+- **Enable Rear Touchpad:** enable/disable back touch mapping to L2/R2
