Consistency Across Games: A highly recommended tip is to create a core set of binds for common actions (jump, crouch, sprint, reload, interact) and keep them consistent across all games. This significantly helps with muscle memory.
Action-Oriented Binding: Instead of thinking "map 'R' to this button," think "map 'reload' to this finger movement.
Prioritize Easy-to-Reach Buttons: Put your most frequently used or "twitch" actions on the most accessible buttons (e.g., downward finger presses or pulls). Less critical actions can go on less intuitive positions.
