Gallery Orderby Options

Hi…

I was looking at the gallery shortcode documentation, and I see that there is an advanced option to do

orderby
specify the sort order used to display thumbnails. The default is “menu_order ASC, ID ASC”.

Only, the documentation does not tell you what the other choices are for ordering. Does anyone know of a simple list of choices?

(p.s. there is another post asking this question but no one seemed to want to answer. Would be great if someone could just simply provide a list of choices. Or am I missing something?)

Thanks.
