No news since a year, is Lightroom dead? I want to be able to copy my keywords in Lightroom for Windows, it really isn't that hard and it's a really basic function.

needs WORK.....we seem to be going backwards. Please complete my keyword and at LEAST let me copy paste it onto a new photo. Not all like photos are in a row.

Hi Rick, thanks so much!  That is what I had been doing and it definitely is better than one at a time.  I also like the early recognition of the word (or suggestion) as you typed so you just type a portion and then move on.

Great idea, Brian! I'll change your post to an Idea so it gets logged as a feature request. In the meantime you can enter multiple keywords separated by commas then copy that string before you hit the "enter" key. That string of keywords can then be pasted into the Keyword field of other images.

It's not ideal, I know, but it's a little better than one at a time.

Yes, I agree. Keywording needs work.
On an iPad I;s like to be able to select multiple images and apply keywords to the selected images!
