Caroline is my niece and Kendall is my younger daughter. Together they are a distructive force not seen since scientists started splitting atoms. No really, these girls can injure an anvil. In thier honor, (and in keeping with the tradition of using some really cool ideas we have seen elsewhere), I give you Caroline and Kendall's Key Question!
Hey, if you want to add to someone else's misery, bring an interesting or unused key, I will implement it into the design when I update it.
