Rather than fiddle with Quote, I've decided to remap Control (which is swapped with Caps Lock). Tapping Control now gives me a Backspace. Shift-tapping Control now gives a Forward Delete.

Added support for Realforce's virtual numpad, found here: https://geekhack.org/index.php?topic=42937.0

Added support re key repeat.
