How to evoke Preview's title bar saving dialogue by shortcut?

Preview shows the currently opened document’s name in its title bar. When hovering over this name, a arrow appears at the right. After a click, there is a dialogue where you can chance the file name, the file tags, the directory and set the file as protected. This is quite handy if you want to add a tag without opening the file's preferences from the Finder view.

How can I open this dialogue using keyboard shortcuts?

Thanks for help.
