At least LazyVim[1] that I use does have visual help for key shortcuts - I can either press the first key (often prefix aka space) and get a popup of continuation keys, or use <space>sk to search keys.

If you only wanted to use that feature, you could install the whick-key plugin that LazyVim uses: https://github.com/folke/which-key.nvim
