When keyframe attributes can't be copied, the other way to accomplish that is to place a copy of the "master" clip elsewhere on the timeline then drag and drop the clip you'd like to match from the Media Library directly onto the copy and choose Replace.

For specific color matching, you can also try selecting the "master" clip and an unedited additional clip then click on the Color Match button. Make sure you have the correct clip in the lefthand Reference window - use the double arrow button above the divider if you need to swap the Reference and Target clips.

You can then select reference frames in each clip and tweak the level and 3 other settings to get the best match

Thank you for your quick response.

Wow, this is a nice trick. After drage a clip from Media Libray and drop it directly over the "master" clip and select Replace, the chroma keys and their attributes are transferred to the dropped clip.

The two clips we are trying to match chroma keys are actually trimmed from the same originally recorded (long) clip. Then we spent time to adjust positions for both clips. Next time we really should apply chroma keys to the original clip first before trimming them. This way, we don't have to worry about copying chroma keys from one clip to another.

This procedure is very useful. What I can see is this procedure only matches color of two clips, but not copy chroma keys from one clip to another. Hope I didn't miss anything here.

You didn't. I think the first method is ideal for your specific situation, while Color Match is better suited when you need to quickly match one clip to another. I wanted to make sure you (and future readers) knew about both options.

Thank you for your confirmation.
