I will soon be purchasing an MBP or iMac. My diabetes may require the imac for my vision issues. I LOVE APPLE's OS!!!! Here are a few questions that I have. 1). I understand that that DEL key is the backspace key. Is there any program to remap another key to work as a delete key? 2). When I go the the URL line and click the line does not highlight like in a Windows OS. Am I doing something wrong? 3). In Windows you can double tap a touchpad "as enter" must you click the single key below on a MAC? Thanks all! You guys are great!
