Thank you!
Works as expected on my unit (350).
I suspect that steman wishes to be able to make notes without selecting text - a kind of dual-tasking: making a note in an overlay-box without closing the book. But your solution is very usable though.
I would have one wish to for christmas
When higlighting text in a book and add a note selected text should be automatically copied into the note. But I expect the solution to be rather sophisticated.
