`:h[elp]` command

[Omnikar]

I think that :h <command> where <command> is a command name from commands.rs would open documentation for the command in the editor, and :h <keybind> would act like :h <command> for the keybind's bound command.

Vim's help system is really good (even though the amount of documentation is a bit overwhelming) and it would be nice if we could have something similar. I propose using markdown to write the docs itself, which has the advantage of being easily hostable in the website and already having the pulldown-cmark markdown parser as a dependency (asciidoc is a better alternative for technical documentation, but we'll have to pull even more dependencies and it's one additional thing to learn).

The issue with markdown is that there is no links between them.

[Omnikar]

I think this should have the A-documentation label?

The issue with markdown is that there is no links between them.

Wikilinks ([[link|optional description]]) are commonly used in note-taking and similar applications. While not being a feature of standard Markdown, it'd be an easier solution than using HTML or any custom markup language (like Vims help syntax). That said, I think more custom syntax would be needed, like different tags for commands, key binds, options, later maybe Wasm API calls etc. These all would be anchors, too, as most note-taking only supports linking documents and headers. Using Vims syntax for these would be easiest probably, maybe wrapped in `` for standard Markdown compatibility:

`:command`
`'option'`
`*xd*` key bind
`api_call()`

Markdown as base for this would be great!

As a new user, this would be very helpful. I've been trying out Helix for the past two days and have basically needed to keep the docs site open in a browser tab to remember the helix-specific keyboard shortcuts that I'm still learning.

A related thing that would also be nice would be a kind of quick help (maybe bound to ?) that would show a popup with the base keys (especially to enter the different modes). I like how the space menu and match menus have little popups that remind you what the available combinations are, but it would be very nice to have a quick way to see what those different modes are in the first place.

second time I was confuzed that there is no :help command. Simple things like how to select lines is not possible to find out inside the editor.

@poelzi have you had a look at the tutor? You can access it using hx --tutor or :tutor from within the editor.

@Omnikar :tutor is great. But it isn't nearly as comprehensive.
