IBM Brand Keyboard Keys--What do they do?

[millerlite86]

This will probably be a really easy question to answer! :-)

Could someone please tell me what these two keys do? (See Attachment)

Information:

IBM USB Keyboard
Model: KU-9958
IBM FRU #:9N5590
Revision: A02

I have this keyboard connected to a non-IBM branded Win2k PC and when I press these keys they do nothing? Anyone know of a driver?

IT might be me but i think that these keys put you forward a page and back a page whenever you are browsing in internet explorer. But its only an ill educated guess.
