Show "available links" on a web page

Description of the issue:
Generally, when you are on a web page, there are several available links to other web pages. For example, if you are on the results page for a web search, there are links to many domains. I prefer using the keyboard & it’s cumbersome to tab through all of the available links to get to the one that I want. Years ago, I remember seeing a web browser feature where you can toggle on a feature in the GUI where the browser numbers the available links. From there, I believe that you could use a keyboard shortcut to visit one of those links.
