I can't change Dave to Dave Smith as I get a duplicate tag error.
What exactly is it that does not work?
Change both tags to not be a People tag (right click the tag, edit keyword tag - remove the check mark next to Person)
Select the ones with the wrong tag (right pointing arrow on the right side of the number next to the tag) and add the correct tag to these files (check mark in front of the correct tag). After that, delete the wrong tag and set the Person check mark on the correct Person keyword.
Thanks for the reply.
I just tried this with some sample images. I tagged faces with test1 and test 2.
These appeared in my people's tags.
As suggested, I edited both to remove the person flag, Selected all Test1 images and changed to Test2, then reflagged as person.
In the keyword list There are no Test1 images and they are all showing as Test 2
BUT when I look at the image the box around the faces still show Test 1??
(Tried to post screen shot but failed)
Cool ... I haven't noticed this quick way
Excellent - Thanks Geoff
