I am a new MBA user and am having a hard time with the keyboard shortcuts. I have had experience with using a Mac but I myself have owned a PC for the past 10 years. Bottom line is im having trouble figuring out what the shortcuts are (especially because of the command button). I just wanted to know: -What are the most useful keyboard shortcuts that you use? -Are all shortcuts used with the command button? -Can I make my own short cuts? -How the hell do I copy and past using the keyboard shortcuts! Thanks!
