How Do I Make A Key Bind Changing System?

As shown on the developer hub page, you can read the KeyCode value of the InputObject, to figure out what key a user is pressing.

local function onInputBegan(input, gameProcessed)
	if input.KeyCode = Enum.KeyCode.F then
		--the F key has been pressed
	end

    if input.KeyCode = Enum.KeyCode.LeftShift then
		--the left Shift key has been pressed
	end
end
 
UserInputService.InputBegan:Connect(onInputBegan)

If you would rather bind specific actions to a function, instead of filtering all input with .InputBegan, you can alternatively use ContextActionService.
