I am using PM 4.5.4 on Mac with 10.5x. Is it possible to select a category of key words and move them into another set? For example, I have an older set named "Mill", in here I have the names of different mills from around Missouri. I would like to create a new set called"Structures" and place the "Mill" set within it. Is there a Drag and Drop function which alludes me? Or do I have to retype it in the new set?
Thanks, Mark
