ICONS on top of i850

[Innealtoir]

I have an i850 that works great. But, in my blissful ignorance, I can find no
reference to the two icons on the top of the case. They are to the immediate
right of the second button. And, I have found no reference to the purpose of
the 2d button.
Your help will be much appreciated.
TIA
Paul

This is the resume button.
