* When a MCE view is selected, normal keystrokes (those without command/control) are blocked.
* Backspace/delete will successfully remove the view.
* Arrow handling will be added at a later point.
* When a MCE view is selected and content is pasted or injected (e.g. when an attachment is added), the content is added to the first text node after the view. If the view is at the end of the document or the next element is another view, a text node is injected into the DOM immediately after the selected view.

These methods should be expanded to prevent content from being inserted into the view by blocking and rerouting keystrokes as appropriate as well as repositioning the caret before content is inserted.
