I've been using Helix for a few months now and it's fantastic. It was a bit rough at the very beginning because I was a die hard Vim user, but after a few days of struggling and paying close attention to the keys I'm pressing, I slowly adjusted and now I'm pretty comfortable.

The one thing I really appreciate about Helix is that all of the features I want are already built in - I don't have to install any plugins nor configure anything. The fact that Helix feels much more responsive than Neovim is just a bonus. Here's my complete ~/.config/helix/config.toml:

  theme = "nightfox"

  [editor]
  true-color = true
  auto-save = true
  line-number = "relative"

  [keys.insert]
  "C-backspace" = ["normal_mode", ":w"]

  [keys.normal]
  "C-j" = ["goto_next_paragraph"]
  "C-k" = ["goto_prev_paragraph"]
  "C-backspace" = ":w"
  "C-h" = "jump_view_left"
  "C-l" = "jump_view_right"

  [keys.normal.space]
  "space" = "goto_last_accessed_file"
  "H" = ":toggle lsp.display-inlay-hints"

  [keys.select]
  "C-j" = ["goto_next_paragraph"]
  "C-k" = ["goto_prev_paragraph"]

If you're just starting out with Helix, go through its tutor `hx --tutor` and if you're wondering why LSP is not working, check out the output of `hx --health` and https://github.com/helix-editor/helix/wiki/How-to-install-th.... Oh and you can search though all available commands with space+?.
