Is it possible to fire a client’s key?

  1. What do you want to achieve? Keep it simple and clear!
    I want to fire a player’s key, ex. Left shift
    I want to make it seem like the player clicked Left Shift

  2. What is the issue? Include screenshots / videos if possible!
    I don’t know where to start as user input service just records when a user clicks something

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    Userinputservice, couldn’t find anything related on developer hub.

I don’t know about it being possible to fire their key, but if you have it setup that there is a function behind the key being pressed, why not just call the resulting function when you want instead of trying to emulate the key?
