Text navigation and selection by dragging finger using one navigation key

To add that, I'd have to remove an existing key to make room for such a key. I couldn't find one that I could easily remove without an uproar from existing users. :)

I see. I don't really want to suggest to remove any of the buttons. My main concern with the current control is that it is too big and I liked the way that navigation worked in the demo.

I have few ideas for you to choose from:

1. Add a control (button) to the existing control that will work the same as described.
   
2. Make the navigation control smaller - consider make it really smaller as whole and additinally (more import), the arrows could threre without the button background and the space around could be transparent (but eventually still available for touch). Maybe some appropriate level of transparency could be useful for the middle part as well.
   
3. Add a "Dot" Button to the center of the screen, it would be an imaginery additinal row. This dot could be useful in readonly mode (without keyboard) too. For sure please add an option (maybe to the top bar next the eye icon) to switch this option on/off because you never know if everybody will like it.

Thanks, I'll see what I can do.
