Need help with understanding more about UserInputService?

Ok, so recently i've come across UserInputService. and i just want to know.. is there a way to detect if a person held a keycode? not clicked? hold?

uis.TouchLongPress:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.E then
		print('Works?')
	end
end)

Somebody please, help me.

No sadly. You Can Use Player.LocalPlayer If Your Doing It On A Local Script
