How do I save my transparent PNG?

[Gooser]

I've got a transparent XCF that I'd like to save as a transparent PNG. I can't seem to figure out the settings in the Save as PNG dialog box. I looked in the Gimp help, but couldn't find any info on this. I also Googled some, to no avail. Can anybody tell me which checkboxes are supposed to be checked in the Save as PNG dialog box?

If you leave them all unchecked, you will still get proper results. They seem to be just options for adding extra optional information to the image.
