Need some direction

[dietpepsi 0]

I am trying to create a script that records how many times the enter key and Function keys are pressed. I am using a system that bills me .8 cents per execution of an command, as defined by the billing policy as the enter key and function keys. It's a database used to look up public records using the BlueZone software. Until I get my bill around the 2nd or 3rd of every month I have no way of knowing how many transactions I have done and/or how much its going to cost. So I'm hopeful somebody can point me into the right direction to start this script.
