Adobe Animate HTML5 Canvas crossword

for a basic crossword where you have to click each square to enter text, the easiest way would be to create a movieclip that consists of white square with black border (and something to show the square's been selected when clicked).  over lay that with a dynamic textfield (eg, tf) and over lay that with a transparent movieclip that will act as a button.  code that button to listen to keyboard input and add that key input to tf.
