CodePlay Playground as you play with the keyboard:

Console

The CodePlay Code Box Editors Playground is very simple to use, anyone can directly interact with a minimum of knowledge of HTML experience, live an idea or a project. We believe that only 5% of the developers has the full capacity and knowledge of each key on the keyboard. Therefore we decided to put together a single command from the Key [Esc] == 27.
For every need and every situation the keyboard [Esc] key fixes and puts in place the Original Initial Code Box Editors.
All this without losing the contents of each Box Editors .
!Enjoy your CodePlay.
