One thing to keep in mind is that some of these shortcut keys predated the modern AT-style keyboard with the function keys across the top. They were introduced way back in the day of the original PC keyboard with function keys in two columns at the left. F1 and F2 were side by side at the top of these columns, and they were very easy to distinguish from each other and hit reliably. F2 was just about the easiest function key for a touch typist to hit. http://www.vintage-computer.com/images/83key.jpg http://www.vintage-computer.com/images/83key.jpg http://www.vintage-computer.com/ibm_pc.shtml http://www.vintage-computer.com/ibm_pc.shtml
