@NanoRaptor The arrows that Apple used for the cursor keys are distinct from the ones on backspace and return, which is great.
I think we all are used to that strange paradigm, where we text- and graphics-cursor are independent most of the time. This isn't the easiest way to so it. We could have another mouse button that toggles between text- and graphics-cursor. Resolution would adapt to the size of the text area, giving you precise control.
