Surface Edit Mode

Quote from agiser

Is there anyone who will make a tutorial video for the surface edit mode?

I can't make one but it's easy.

1. Take the block in an active slot

2. Turn on surface edit with alt gr (right alt key)

3. Use ctrl + arrow and pg up/dn key to move the surface in any direction. Use shift + arrow or pg up/dn to change size

4. To turn off this mode, hit the alt gr button again

Quite simple. 😬
