This is a terrific idea and thank you for suggesting it. I love the idea of 100% keyboard navigation. I downloaded tridactyl and fixed a ton of issues. I also made some judgement calls on those context menus. When I hooked up every context menu in both the feed list and story list, everything because double-letters. It was chaos. So I dialed it back and just gave context menu access to the story titles.
I also hooked up the Infrequent Sites Stories and other top header feeds. Unfortunately I must not be using the extension right because I could get them to work, I wasn’t able to switch back and forth repeatedly, either due to operator error or there’s something more fundamental that I’m missing. It works the first time, but after that tridactyl seems to prefer the hover state over the click state. Maybe that’s a preference or keyboard command I didn’t know? Let me know how it works for you, happy to make adjustments.
And I confirmed you can now rename a feed without leaving your keyboard.
