Grammar jacks script

Hello, I'm looking to buy a script for a game called roblox. These "grammar jacks" are basically jumping Jack's but you say the number in the ingame chat. (Jump (/ to chat) in chat, you would say "ONE". Jump, and in chat type TWO etc.) But it has to look like a human is typing it. So have a 3 second delay after jumping to type. It will also need a toggle on/off hotkey, and a place for me to change how many I need to do.
