I got the following email question (slightly rephrased):

Q: I select many photos with Ctrl-Click and try to apply some keyword to all the photos. It just doesn’t work. The keyword is applied only to the first photo.

  1. In the develop module, switch to the Grid View.
  2. If there is more than one monitor, switch to the primary monitor.
  3. Make sure that: Menu > MetaData > Show Metadata for Target Photo Only is unchecked.
  4. Select all the photos for the keyword.
  5. Drag and drop the keyword onto one of the selected photos.
  6. Done.
