Is there a shortcut or keystroke that would allow me to enter a caption for multiple photos at the same time by selecting them in the filmstrip and viewing a single large photo on top. One photo in the filmstrip has a white outline, the others gray. I'm forced to go back to one of the tile modes to select multiple photos, enter the identical caption, go back to individual photo mode & then proceed with other editing. Seems this MUST be possible from the filmstrip.
