Enter fails to confirm in the New Document dialog after editing values

[DallinYauney]

In the New Document window, hitting enter after typing the name, or the resolution, should confirm (just like clicking OK). It currently works only if those values haven't been changed.

I'll usually click OK if I haven't adjusted any of the defaults, but it feels super weird to type something, and then use my mouse to finish what has become a keyboard-based task, so I always end up hitting Enter and then remembering it doesn't work like that.
