Add ability to replicate pan behavior as seen in native keyboard view.

[illyabusigin]

I'd like to implement a behavior found on the iPhone's system keyboard: user touches a key, and other keys are highlighted as the finger drags across the keyboard. When the finger lifts, the last highlighted key inserts the text. If user long-taps a key, then its expandedInputView pan gesture is tracked instead of the entire keyboard.

Yes. How can we do that one? I am modifying this library and still not okay. Can anyone advice?
