X11, keypad overlay. What is that?

I was perusing the keyboards X11 drivers, the file /usr/share/X11/xkb/symbols/keypad catch my curiosity.
Do anyone knows what the keypad overlay is?
Thanks

From this site http://anakin.ncst.ernet.in/~aparna/con … x1740.html
It says...

Symbols
These tables map each symbolic keycodes into the character encoding for a particular language. For every keycode all possible symbols are specified which, depend on the key types (described earlier). Which means that for each specific case of keycode the symbol values depend on the modifier state and their behaviour. The behaviour of these modifiers are defined in the files in the directory <XKBdir>/compat/. symbols are located in <XKBdir>/symbols directory. Each supported language finds its entry in this directory. If you don't find an entry for your language, then you will have to create one(described later).

Interesting general read, but it does not explain the overlay1 section of /usr/share/X11/xkb/symbols/keypad at all.

Well actually it does... more simply it says that the file /usr/share/X11/xkb/symbols/keypad is a table that map the symbolic keycodes of your numpad...
So basically it is the files that says that the keycode X = the Left arrow on your numpad, or the Home button, etc..
