Two editors are available: the Code Editor and the Visual Editor.
Code Editor
The code editor mode is an HTML editor designed to let you inspect every elements and directly modify your layout. You can delete, modify, update, copy/paste, drag and drop every elements that you want.
The HTML mode includes a few helpers such as auto-completion for document properties, tasks properties, functions and polymer behaviours. The annotation @doctype, @schema or @task defined for each property defines the auto-completion for that property.
