+signal to the Helix process on Unix operating systems, such as by using the command `pkill -USR1 hx`.

+

+### `[editor.auto-pairs]` Section

+

+Enables automatic insertion of pairs to parentheses, brackets, etc. Can be a

+simple boolean value, or a specific mapping of pairs of single characters.

+

+To disable auto-pairs altogether, set `auto-pairs` to `false`:

+

+```toml

+[editor]

+auto-pairs = false # defaults to `true`

+```

+

+The default pairs are <code>(){}[]''""``</code>, but these can be customized by

+setting `auto-pairs` to a TOML table:

+

+```toml

+[editor.auto-pairs]

+'(' = ')'

+'{' = '}'

+'[' = ']'

+'"' = '"'

+'`' = '`'

+'<' = '>'

+```

+

+Additionally, this setting can be used in a language config. Unless

+the editor setting is `false`, this will override the editor config in

+documents with this language.

+

+Example `languages.toml` that adds <> and removes ''

+

+```toml

+[[language]]

+name = "rust"

+

+[language.auto-pairs]

+'(' = ')'

+'{' = '}'

+'[' = ']'

+'"' = '"'

+

+Example

+

+```toml

+[editor.whitespace]

+render = "all"

+# or control each character

+[editor.whitespace.render]

+space = "all"

+tab = "all"

+newline = "none"

+

+[editor.whitespace.characters]

+

+### `[editor.gutters]` Section

+

+For simplicity, `editor.gutters` accepts an array of gutter types, which will

+use default settings for all gutter components.

+

+```toml

+[editor]

+gutters = ["diff", "diagnostics", "line-numbers", "spacer"]

+

+Example:

+

+```toml

+[editor.soft-wrap]
