How to have arrows for moving the cursor right and left when writing text on iPad? On an iPhone, I was writing text. Among the keys, I have seen arrows for moving the cursor right and left.

How can I have these keys on iPad ?

These would be very useful.

Why aren't these keys present on iPad ?
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.
