However, something that I’ve instantly fallen in love with in Writing Kit is that on the iPad, the left and right margins act as left and right arrow keys. Tap the left margin to move the cursor one character to the left; tap the right margin to move the cursor one character to the right. This clever little feature is like Pull to Refresh — once you’ve used it it instantly feels natural and you miss it in every other app.
Genius! I've always felt like text selection in iOS is as good as it gets with a touch device, but this is much cleaner.
