How to *smoothly* add keywords to several non-indentically tagged pics?

[Henrik2000]

Hello, tagging with keywords in Bridge CC (preferred over Lightroom Classic), I often want to add one more keyword to several images in a row that already have various non-identical keywords. I want to add the new keyword(s) so that the existing keywords remain there and are not replaced, but added-to. I think LR has a specific field to type keywords into; they will be added to selected images, but existing keywords remain.

Example:

Image A:

Existing keyword 1: beach

Existing keyword 2: sunset

Image B:

Existing keyword 1: street

Existing keyword 2: traffic light

Both images should receive the new keyword icecream, while the existing, non-identical keywords remain in-image. But when I select both images in Bridge, open "File Info" (translating menu commands here from other language) and type the new keywords, the old keywords are lost. I believe only LR has the small box that accepts keywords as additions, not replacements.

I found these ways to add – not replace – keywords to several selected images in one go in Bridge, but none is totally satisfactory:

1. 1. way: In Keywords panel, right-click on Other Keywords, add a new keyword, select your images and click into the desired keyword's check-box in the Keywords panel.
2. 2. way: Select only one image, open File Info, type the new keywords in, the existing ones will remain, and close. Wait (patiently) until the fresh keywords appear in the Keywords panel, select the other images and click into the keyword's check-box in the Keywords panel.
3. 3. way: For more often used (groups of) keywords, create metadata templates. They can be easily applied to selected images by menu command Add Metadata (not Replace Metadata)
4. 4. way: For rarer keywords, create a generic metadata template called "1 metadata" (so it's alphabetically on top), fill it with your keywords du jour, save, select images, apply.

I am also aware of hierachical keywords and of importing tabbed text files as keywords. But I use many keywords and I am a fast and safe typer. On the other hand, my Keywords panel gets way too long very quickly, even if I empty it all the time; I don't like to use it. My list of metadata templates has grown too long too, but you can easily clean up by moving or deleting some xmp files.

Do you know a smoother way how to rapid-add keywords to several, already non-identically tagged images in Bridge?

  Thanks!

Copy all of the clearly styled code.

Perhaps take a look at the updated code posted by @gregreser instead.

Amazing. Thank you so much! Can't believe Bridge doesn't have an Add to Meta Data tool within it's regular UI.
