/*! jQuery UI Virtual Keyboard Typing Simulator v1.12.0 *//*
* for Keyboard v1.18+ only (2019-05-02)
*
* By Rob Garrison (aka Mottie)
* Licensed under the MIT License
*
* Use this extension with the Virtual Keyboard to simulate
* typing for tutorials or whatever else use you can find
*
* Requires:
* jQuery
* Keyboard plugin : https://github.com/Mottie/Keyboard
*
* Setup:
* $('.ui-keyboard-input')
* .keyboard(options)
* .addTyping(typing-options);
*
* // or if targeting a specific keyboard
* $('#keyboard1')
* .keyboard(options)
* .addTyping(typing-options);
*
* Basic Usage:
* // To disable manual typing on the virtual keyboard, just set "showTyping"
* // option to false
* $('#keyboard-input').keyboard(options).addTyping({ showTyping: false });
*
* // Change the default typing delay (time the virtual keyboard highlights the
* // manually typed key) - default = 250 milliseconds
* $('#keyboard-input').keyboard(options).addTyping({ delay: 500 });
*
* // get keyboard object, open it, then start typing simulation
* $('#keyboard-input').getkeyboard().reveal().typeIn('Hello World', 700);
*
* // get keyboard object, open it, type in "This is a test" with 700ms delay
* // between types, then accept & close the keyboard
* $('#keyboard-input')
* .getkeyboard()
* .reveal()
* .typeIn('This is a test', 700, function(keyboard) {
* keyboard.accept();
* });
*/
/* More Examples:
* $('#inter').getkeyboard().reveal().typeIn('\tHello \b\n\tWorld', 500);
* $('#meta')
* .getkeyboard().reveal()
* .typeIn('abCDd11123\u2648\u2649\u264A\u264B', 700, function() {
* alert('all done!');
* });
