#1 Can't TAB from title field to content field

[Mike King]

Issue:
-------
While typing in the title field of the main screen, if you hit TAB, a TAB
character is inserted into the title field.

Expected Result:
--------------------
While typing in the title field of the main screen, if you hit TAB, the cursor
should jump to the content textarea.

Additional Info:
-----------------
While typing in the content field, if you hit TAB, the "Post" button should
be highlighted next.
