I'm all but decided on a Macbook Pro 15 but when I went to the Apple Store to pull the trigger they were too busy and didn't have anybody to help me. While I waited I was playing around with a demo unit and realized that there are two things that really seem to bother me: 1. There is no page-up or page down keys. Is there any way to emulate these? 2. In Excel I can't use the function keys like I do in the PC. (For example, pressing F2 to edit a cell or F4 to switch between relative and absolute references). Is there any way to make Excel operate on the Mac the same way as it does on a PC? I'm willing to change but some old habits die really hard. In the case of Excel I'm never going to be able to stop using the PC version in the immediate future. I can't seem to find suitable answers to these questions anywhere, but if this isn't the right forum to ask this question, I'd appreciate a polite nudge in the right direction. Thanks.
