edit/change metadata in Info Panel?

[ceej]

I have seen at least one YouTube video in which a person is using XNView, selects a thumbnail, a large preview appears, and next to it is an Info Pane (with Properties, exif, xmp, exiftool tabs). In the video the user clicks/double clicks/does something in a field in the Info Pane which makes that field editable. Is that really possible, and how do I "make it happen"?
If one uses Windows Explorer, one can set the View option to Details Pane, in which one can edit various EXIF fields - including DateTaken, Title, Authors, comments, Camera make/model. One can change those fields for a single image, or select multiple images and apply the changes to all the selected images.
Thanks,
