Feature Request: Enabling "Link Hints" in Gnome Files

Background

I’m trying to minimize mouse usage in my workflow. For my browser, I use an extension that enables me to press f to see “link hints” for all clickable elements (links, inputs, buttons, etc.).

Feature Request

I would like to have similar functionality in Files (Nautilus). Since f triggers the default search, another hotkey should be assigned, maybe Alt+F. I particularly need this for elements in the sidebar, as I frequently switch between bookmarks and find keyboard navigation to them cumbersome (it seems there is no existing shortcut?). This feature could also display hints for currently clickable buttons throughout the interface.

That seems like a feature for Orca or other accessibility tools, not individual apps.
