- Opening files in a split moved from `C-h` to `C-s`
- Some configuration options moved from a `[terminal]` section to `[editor]`. [Consult the documentation for more information.](https://docs.helix-editor.com/configuration.html)

# Adding Textobject Queries
Textobjects that are language specific ([like functions, classes, etc][textobjects])
require an accompanying tree-sitter grammar and a `textobjects.scm` query file
to work properly. Tree-sitter allows us to query the source code syntax tree
and capture specific parts of it. The queries are written in a lisp dialect.
More information on how to write queries can be found in the [official tree-sitter
documentation](tree-sitter-queries).
Query files should be placed in `runtime/queries/{language}/textobjects.scm`
when contributing. Note that to test the query files locally you should put
them under your local runtime directory (`~/.config/helix/runtime` on Linux
for example).
The following [captures][tree-sitter-captures] are recognized:
| Capture Name |
| --- |
| `function.inside` |
| `function.around` |
| `class.inside` |
| `class.around` |
| `parameter.inside` |
[Example query files][textobject-examples] can be found in the helix GitHub repository.
