With Scrivener for iOS waiting in the wings for its entrance, I thought I might post this description from Apple about new features of the touch keyboard on iPads in iOS 9. Note that these are iPad features. Apple apparently decided my iPhone 5 screen was too tiny for them to work.
Using two fingers as cursors keys is particularly nice. One weakness of iOS has been the messiness of selecting text. This makes that better for situations where users don’t have an external keyboard.
One added note: Those who’d like to find a foldable keyboard to use with their iPhone might want to look (i.e. on ebay) for one of the few Palm keyboards that does, the Palm 3245WW.
