Comment 3 for bug 894399

1) The toolbar floats over and blocks the topmost lines of
the editing area. So your first proposal is not feasible.

2). Requiring new users to learn a new keyboard shortcut to
show the toolbar is not good usability. Especially since new
users are most likely to use the toolbar. Keyboard shortcuts
are great for advance and experienced users.

3). See point 1.

If you find the trigger area distracting hiding it is the
simplest and best option. I can provide a keyboard shortcut
for that, or you can just disable the trigger area plugin
so it doesn't load.
