Environment

• __Package version(s)__: 3.35.0
• __Browser and OS versions__: Any

Feature request

Add an onEnter callback to EditableText or extend the onConfirm callback with information on what triggered the confirm (enter or blur).

Examples

I'm using the EditableText on todo's. When the user hits enter I want to start another todo, but not when blurred.
