The code provided for Smartkeyboard on IPad Pro seems to be broken, so
am making minor changes to try to fix this.
The following should still function, but this will need testing by an
IOS user with this hardware, if it compiles.
These have not been compiled or otherwise tested, but are cleaned up
version of code changes from forum user "dottostring" in thread:

This should add Fake ESC key support replacing the '`' key and add full
support for the Arrow keys.
