Accessibility suggestions

At the moment, there is no way to TAB across each editor-block, because TABBING enters a block, and there is no way for keyboard users to exit a block.

@sergejspomer and myself discussed accessibility suggestions.

Accessibility suggestions

• when user tabs through editor-blocks, only enter an editor-block when user presses ENTER or starts typing something (any key that is not TAB, ESC, or SPACE) (the preferred option).

• when user presses ESC key while inside an editor-block, leave the editor-block (i.e. take the editor-block out of focus)
