Normal 101 keyboards on Mac keys correspond

For convenience, engage a regular 101 wired full keyboard + Magic trackpad with MacBook. Then found a small problem, the button correspondence does not seem to be as perfect as I thought, f1~f12 and MacBook do not correspond, so, began to try the button.

The blue area represents the same key functions as the Mac keyboard and the normal keyboard keys.
The red area represents the keys that I now know are different from the prints on my Mac.
Purple areas represent keys that are not yet clear.

①windows key ====command (this one knows)
②alt Key ====option (this one knows)
③f11 key = = =

④f12 key = = = = Show Dashboard
⑤scroll lock = = Reduce screen brightness
⑥pausebreak key = increase screen brightness
①insert key: Press the mouse will become "? ", meaning unclear.
② the right key of the Windows key: The meaning is unknown.
③F1~F10 key: It seems that only as a standard function key, it seems to find no special function (press the mouse will disappear, the dynamic trackpad will appear again), and trigger the standard function keys do not need to fn+f1 (in preference settings do not select the hook will F1, F2 and other keys set as the standard function keys). Press and hold the FN on the MacBook, and then press F1~F10 on the normal keyboard to not respond.
④numlock key: No matter how to press the keypad LED is not lit, but even if it does not light can be normal use of the keypad

The amount, is the FN key is not, usually FN is used to press FN dictated by two. In addition, please seal the glaze to share what other combinations of keys or I found every key function.
