Just noticed this while doing this entry. You can't use the arrow key to press back and forrth to edit the text in this text box. You also can't shift-select, copy, cut, or paste. Home, End, etc also don't work. I'm sure you have that in the works, i haven't read everything yet.

Also, there are a few other keyboard shortcuts that make things very convenient. For example Alt+Left or Right arrow to go backwards or forwards. Backspace when you're not focused in a text box is a shortcut for the back button in both IE and netscape - I use that very often and it was frustrating when I first started using this.
