There are several shortcuts that can help when working with keywords in Lightroom:
• Command + K (Mac) | Control + K (Win) will highlight the Keyword text entry field.
• Command + Shift + K (Mac) | Control + Shift + K will highlight the larger, Applied Keyword box above it.
In addition, the Painter tool can be “loaded” with a keyword(s):
• Command + Option + Shift + K (Mac) | Control + Alt + Shift + K (Win) will display the Set Keyword Shortcuts dialog box where you can set the Painters tool’s keyword. Then, with the Painter tool, simply click on any image in the Grid view to apply that keyword. Click-drag across multiple images to apply the keyword to several images.
• If the painter tool is set to apply keywords, Shift + K will remove the Painter tool’s keyword from the image.
Finally, Option + 1-9 (Mac) | Alt + 1-9 (Win) applies keywords from a keyword set when using the number pad on an extended keyboard. Holding the Option + (Mac) | Alt (Win) key displays the numeric shortcuts next to the Keyword Set so that you can see which number will apply what keyword.

Hi Julieanne,
I attended your seminar at PDN Expo this year and then an Adobe Walk in NYC. Both were great. I learnt a lot from you. Unfortunately, still have some questions.
First of all, on keywording. I tried to keyword pictures with the Painter following your instruction above. They showed as marked by the Painter but the keyword was not added to them. Shouldn’t it be seen in the keyword window?
Thanks.

Yes, when you use the painter tool to apple a keyword, the keyword should then appear in the keyword panel. I am not sure why it wouldn’t… If you click on the photo with the keyword, does LR add it?
Julieanne, I know what was wrong. I didn’t pick “keywords” for the painter. it was set on “flags”. Sorry.
Hi Julieanne;
What’s the difference between the 2 Keyword text entry fields?
Lou
The one that says “Click here to add keywords” allows a person to add a keyword without interfering with keywords that are already applied in the region above. I don’t know of any other differences, but if you do, please chime in.
