I don't know how keyboard input is implemented on the OS side, but here's  
an overview of the protocol used by the Newton Keyboard:

Note: this is from a German keyboard, which has keys arranged slightly  
differently compared to an English one.

The key codes are a subset of those of the Apple Extended Keyboard II; see  
page 326 of the PDF of the Newton Programmer's Guide for Newton 2.0.
