How to have arrows for moving the cursor right and left when writing text on iPad?
Solution 1:
At this point, there is no default functionality on the iPad for arrow keys. (I suppose the idea is to tap the text to position the arrow). There is a chance that there is a 3rd-party keyboard for iPad that would include arrow keys.
Those arrow keys, from what I have seen, are unique to the iPhone 6 (and Plus) while in landscape mode.
Because of the way that the iPad can be typed on (two-handed vs. two-thumbed on the iPhone), there is a chance that arrow keys will never be brought to the iPad's default keyboard.
Solution 2:
Try holding two fingers at same time anywhere at virtual keyboard and you should be able to move cursor / marker left - right (keyboard letters become invisible in the meantime) using ios 9.x.x.
