Tidying my Keywords list
I imported all my images from iPhoto a few weeks ago, having bought Aperture 2 then. Of course it imports the iPhoto keywords into a sub-list. I now seem to have duplicated keywords all over the place - some in the iPhoto sub-list, some in the root list. I've even managed to get some with different case starting letters (i.e. vacation and Vacation).
I haven't actually added many new keywords, as I've not been out taking many new photos lately, so all of these have appeared of their own accord.
I also only use photos for my personal needs, so I don't need dozens of sub-categories either.
Is it possible to re-organise/tidy/merge all my keywords without having to re-enter them into the images? (I have 30,000 in the Library).
Cheers.
