A:AnswerI have not had any issues with double typing although I have read some threads on reddit about customers having this problem. Apparently it is something to do with the software of they keyboard so try to update it, or if that doesn't work you can always program the keys to do what you wish I believe.
A:AnswerNot sure why they don’t. That’s up to them. But they can’t have every keyboard. Not enough room. They do also ship and have a lot more stuff online. Believe free shipping if you pick up at the store.
