I have quite bad arthritis in my hands, and I'm finding the keywording process more and more frustrating because of one simple issue.
When keywording multiple images, many of the keywords show up as light grey when they only apply to some of the selected images. I want to select these to add them to all selected images. However, unless the mouse is COMPLETELY still when clicking, all you do is to move the keyword slightly. It doesn't apply to all images.
I end up clicking on a keyword, it temporarily darkens, then goes back to grey because my mouse moved by one nanometre.
