Having used pc's for many years I have finally moved over to a 24" iMac. With the pc I can allocate quick keys on the mouse buttons for applications such as photoshop, Illustrator etc. ie. right side button to "crop from selection", scroll button to open "curves" & left side button to "save as" etc. I have not found a way to do this with the iMac & mighty mouse. My question is, can it be done? Regards Ripple
