Key Grabber Library - DFRobot LCD Shield

Here's the first version of a key grabber library I wrote for this shield as I'm using it in a project for work, and the LCD4bit_mod library was... clunky.  I see that there's another new library for it, if it's better, perfect, if not, you can include this (DFR_Key) library to handle keys while LiquidCrystal handles the LCD functionality.  The library includes a very simple example of how to use it.

Project: https://sourceforge.net/projects/dfrkey/

Hopefully it's useful!  Contact me with questions/comments.

P.S. I'm using the board in conjunction with the "official" XBee shield and some other hardware, so I'll be posting on good ways to use available DIOs, and how you can sandwich the XBee shield in there, should you feel the need.
