The Help for "Apply Subject and Sky masks in batch edit" has several errors. It says:
"1. Open a photo in the Develop module.
...
3. Click Copy at the bottom of the Presets panel...
4. ...select the photos you want to paste the mask to. You can use the filmstrip for this.
5. Once the desired photos are selected, click Paste. You can also press Ctrl/Cmd-V."
- The section title should be "Apply AI masks in batch edit", since the instructions apply to all types of AI masks.
- Step 5, clicking Paste, won't update all the selected photos in Develop or in Library Loupe -- it will only update the most-selected photo.
- The shortcut for Paste is Shift+Ctrl/Cmd+V, not Ctrl/Cmd+V. And Adobe's convention is to use "+", not "-", in keyboard shortcuts.

The instructions should be rewritten to use one of the methods that does work:
- Do the Copy/Paste Settings in Library Grid view.
- Use the Sync Settings command.
- Right-click one of the selected photos and do Develop Settings > Paste Settings. (Yes, that behaves differently than the Paste button or the main menu command Photo > Develop Settings > Paste Settings.)
