Now this might be an odd question

I have a client who has the dell vostro 1710. He wants to know what all the keys mean. (not the basic but all the other keys). I have looked all over dell's site and i cannot find a manual that shows all the keys. One shows all the items on the sides of the laptop but not what each function the keys do and i am not talking about the basic I am talking about the fnc keys, etc
This did not come with the laptop. Has anyone know where one is?

I went and took pictures of our 1510 laptop- it is similar it is just missing the calculator keye. Now i have to make a word file and show him which key is which- a royal pain in the butt. Or I have to go back to his home which is about an hour from me to again show him the keys again which i really do not want to do.

Any ideas where i can find one that has pictures and tells what each key means?
