Reordering tabs in MacOS Safari

Member of the AppleVis Blog Team

Does anyone know how to reorder tabs in MacOS Safari?

I've tried going to the tab in the tab bar, then hitting VO+Command+accent. VoiceOver tells me "tab cannot be moved". I'm not sure why. Sighted people can move the tabs by dragging them with the mouse. There must be a way to do this accessibly.

Thanks for any help.
