Expanding Player Key Input Support in Predicates

Hello Mojang Studios Team, I am a Minecraft Java Edition datapack developer and would like to ask about a possible expansion related to predicates and player input detection. At the moment, predicates can only detect a very limited set of player actions or states. In contrast, resource packs—specifically model overrides—already support a much broader and clearly defined set of inputs through key_bind, including keyboard keys and mouse buttons. I would like to ask whether it would be feasible to expand predicates so they can detect the same range of player inputs supported by key_bind, effectively aligning both systems to use a unified set of input definitions. For example, predicates could allow checks such as: • Whether the player presses the Esc key • Whether the player clicks the left or right mouse button This would significantly enhance datapack capabilities for advanced minigames, custom interactions, and UI-like mechanics, while remaining server-side and without requiring client-side mods. I understand there may be design or performance considerations, but I would appreciate knowing whether this direction aligns with the long-term plans for commands and datapacks. Thank you for your time and for your continued work on Minecraft. Best regards, Nox_Obscura
