After seeing this comment by @daredevil, and the reply by @dellyphy, I was inspired to create a userscript that adds keyboard shortcuts to make using kbin a bit easier.

I haven’t figured out how to add shortcuts for navigating and interacting with stuff, but I’m working on it! I’ll let you know once I’ve gotten something working.

If you don’t have a userscript manager extension, you can install Tampermonkey, FireMonkey (Firefox only), or Violentmonkey, and then install the userscript through the greasyfork page.
