Bob Shaw - I find the delete key irreplaceable for deleting characters to the right of my cursor (and backspace for characters to the left of my cursor). I never understood why Apple doesn't include this key. And, I find it retro and amusing that some Mac users still feel compelled to make stupid remarks about Windows users. Damn.
Randy Carone - Unlike your post which provides no benefit to the OP, I actually tried to assist them. On a Mac Command-P is print and Cmd-C is copy and Cmd-V is paste and on a PC Control-P is print, Ctl-C is copy and Ctl-V is paste. It would seem logical then that Command-D on a Mac which is Duplicate would be the same as Control_D on a PC.
I mean, who would have thought that a 21st century computer would not have a single keyboard combination to duplicate a file? I use this combination continually in uploading new PHP files to the web. You duplicate the file with Cmd-D, open the file, make the changes, Cmd-S to save and then upload anything newer than the one on the server. There are no "Paste As" options to trick you up.
As for Macs not having a delete to the right key, well the amusement is all in your mirror. As far as I know they have always had one. It is staring at me to the right of the Delete left key. Perhaps you have only used the basic keyboard and not the usual Extended Keyboard? I have nothing against PCs. I encourage all of my competitors to get one.
Macs also read raw files in the operating system so you can see them on the card before you even upload them. Neat eh?
