It's both.

Not yet. It should be possible, but it won't be easy because it two very
messy parts of Leo:
1. Translation of key codes to "canonical" key representation. This is
done in the eventFilter method of the leoQtEventFilter class. This code is
not only unbearably ugly, but it may also be keyboard specific.
2. Translation of user settings to canonical key representation. This is
done in the keyHandlerClass class in leoKeys.py, specifically the nest of
methods at:
leoPy.leo#Code-->Gui base classes-->@file leoKeys.py-->
class keyHandlerClass-->k.Shortcuts & bindings
For instance, I want to use 'Keypad-Insert', 'Keypad-minus', 'Keypad-plus'

This would be a reasonable addition to Leo. Feel free to file a wishlist
bug at: https://bugs.launchpad.net/leo-editor
A quick check of the Qt QKeyEvent class shows that key events have a
KeypadModifier
bit in the KeyboardModifier field, so it should be possible to distinguish
keypad keys. It's just that Leo doesn't do it. And as indicated above,
the change is not entirely trivial ;-)
