Google Maps API v3 add another button next to undo button when drawing a Polygon

Question

I'm working with Google Maps API v3. When you edit a polygon, an "undo" button appears next to updated vertice.

I'm absolutely sure I've seen some times ago someone posting a jsfiddle where he demonstrates how to add another button next to this undo button, but I can't find it whereas I'm seeking for this link for 1 hour. It wasn't on geocodezip's website but I can't find its topic.

Can someone show me where I can find this implementation ? Thank you very much.
