1. In the Data Type constraints modal, when adding "Enumeration", after the string is typed if user press "Tab" the focus goes to the cancel button (the X) instead of the "V" button (the apply).
2. I think is not clear how to apply with keyboard shortcut. In the Data Type tab, CTRL + S saves, but in this modal CTRL + S calls the default browser behavior. I think it have to be consistent.
