How can I add items to the right-hand panel of the edit dialog?

I’m not sure what terminology to use here, but look at the screenshot of the dialog window that appears when I double-click a tag such as XMP:Subject. The right-hand side of this dialog looks like it could be populated with a list of items, I’m assuming for quick access. Is that possible? Or is this portion of the dialog not really used for anything? I’d love to be able to put frequently-used items there, if possible.

Hello,

When you see this panel, it means the tag is defined as a Word List. From the main menu bar, you can open the Keyword Panel to add or remove keywords, create new word lists, and more.

Once you’ve added your preferred keywords to the list in the Keyword Manager panel, they will appear on the right-hand side of this panel. You can then easily insert them by simply clicking on them, ensuring consistent use of the same words each time.

I hope this clarifies things!
