There are three kinds of commands that can be used in keymaps:
* Static commands: commands like `move_char_right` which are usually bound to
keys and used for movement and editing. A list of static commands is
available in the [Keymap](./keymap.html) documentation and in the source code
in [`helix-term/src/commands.rs`](https://github.com/helix-editor/helix/blob/master/helix-term/src/commands.rs)
at the invocation of `static_commands!` macro.
* Typable commands: commands that can be executed from command mode (`:`), for
example `:write!`. See the [Commands](./commands.html) documentation for a
list of available typeable commands or the `TypableCommandList` declaration in
the source code at [`helix-term/src/commands/typed.rs`](https://github.com/helix-editor/helix/blob/master/helix-term/src/commands/typed.rs).
* Macros: sequences of keys that are executed in order. These keybindings
start with `@` and then list any number of keys to be executed. For example
`@miw` can be used to select the surrounding word. For now, macro keybindings
are not allowed in keybinding sequences due to limitations in the way that
command sequences are executed. Modifier keys (e.g. Alt+o) can be used
like `"<A-o>"`, e.g. `"@miw<A-o>"`

> 💡 To set a modifier + key as a keymap, type `A-X = ...` or `C-X = ...` for Alt + X or Ctrl + X. Combine with Shift using a dash, e.g. `C-S-esc`.
> Within macros, wrap them in `<>`, e.g. `<A-X>` and `<C-X>` to distinguish from the `A` or `C` keys.
