When I try to edit a misspelled key word through Edit Keyword I get a message indicating that it already exists and to choose another. Since I habe the mispelled Keyword on a large number of pictures it would be tedious to correct each one at a time. Anyone have an idea how to do a batch correction of a keyword?
Select all images with the mis-spelled keyword, then in the keywording panel, change the spelling to the proper spelling
...and then delete the misspelled keyword from the Keyword List.
