Text editing in HTML5 canvas with Konva

User can’t directly edit Konva.Text content. In fact canvas API is not designed for such purpose.
It is possible to emulate text editing on canvas (by drawing blinking cursor, emulate selection, etc).
Konva has not support for such case. We recommend to edit the user input outside of your canvas.
It may be textarea somewhere in your page.

Instructions: Double click on text to edit it. Type something. Press Enter.
