What does __unkeyed mean?

[Readf0x]

While looking at the documentation for which-key, I noticed that it uses __unkeyed and __unkeyed-[n], but I could not find anything stating what that meant, on the nixvim wiki or in the which-key documentation. I'm relatively new to nix, and do not particularly feel interested in digging through the source code to figure it out myself. So an explanation would be immensely appreciated, thanks!

Apologies, looking at the example again, it clicked. I'm very disappointed there is not a "delete discussion" options, as this discussion entirely useless.
