Change behavior of toolbar in browsers not supporting document.selection:

Change behavior of toolbar in browsers not supporting document.selection:
- When the mouse is moved over the buttons the infobox shows an example text
- When the user *clicks* a button, he is prompted to enter text, which is
  then formatted according to the button they chose and inserted into the
  infobox
- After the first button has been clicked, the infobox no longer changes
  on mouse move to allow for copy and pasting.

This could be modified to add an additional [+] button that pastes the
content of the the infobox into the textarea, but I've tried this and found
it confusing.
