Support numpad keycodes

[hatmix]

Feature Description

(This is actually a minor bug, but a bigger enhancement request...) If a numpad keycode, KEY_KP_* is encountered, it causes the error Invalid get index 'Kp...' (on base: 'Dictionary') because the KEY_KP_ entries are missing from the _KEYS array. Quick fix is to add those to _KEYS, however this just leads to an empty texture. That can also be addressed (one way is to parse out the "Kp " before looking for the texture), but it leads to a bigger question. How can the UI differentiate between numpad keys and their non-numpad equivalents?

Is there some way I missed to handle this?

If I haven't missed something, I imagine two possibilities. Show two textures for numpad keys (numlock and the key), or use a color to differentiate (red is already used in the high-res Kenney icons, so this seems reasonable).

The meaning of the red color for numpad keys might be explained by adding a keyboard representation colored the same way (for example, imagine extending the keyboard below with a red keypad)

(Keyboard is from openclipart.org, the rest is from Kenney's)

What do you think? Have you dealt with this a different way?
