Which is the enter key

Usually the menu button (the button with the 3 lines).

I believe the enter key isn't on the keyboard to make room.

But it is the menu button, like said above.

Its the start button, it has 3 lines

Hey Joseph,

Thank you for posting here on the Xbox forums. Normally, the menu button will act as the enter button when the keyboard is up. The start button is a little black button in the middle of your controller, to the left of the X button. It has 3 horizontal lines
on it. You can also select Enter from the keyboard if you still have it up.

Hope this helps!

the enter key is above the shift key and below the |\ key and the ]} key correct? 1 enter

2 enters

3 enters

there I press enter, happy!

I'm 29 years old man! I have a sense of humor, in which you apparently don't. But everything I wrote I've noticed that's what COD players are like.
