We use both PC and Mac depending on whether it is in the still photo editing (mac) area or video (pc) side of the office.
I guess what I'm really asking for is the ability to use CVKC while in an individual file's IPTC Info page to assign keywords. We get many photos from different sources routinely and edit them in large batches. So, we might only have one photo showing X, three showing Y and the rest showing Z. So, we really don't have the ability to load a single group of keywords.
If we could save some screen real estate and have access to the CVKC in the IPTC Info window keyword area it would help tremendously with taxonomy.
