multiple indent level increases that start on the same line only increase
the total indent level by 1. See [Capture types](#capture-types).
By default, Helix uses the `hybrid` indentation heuristic. This means that
indent queries are not used to compute the expected absolute indentation of a
line but rather the expected difference in indentation between the new and an
already existing line. This difference is then added to the actual indentation
of the already existing line. Since this makes errors in the indent queries
harder to find, it is recommended to disable it when testing via
`:set indent-heuristic tree-sitter`. The rest of this guide assumes that
the `tree-sitter` heuristic is used.
## Indent queries
When Helix is inserting a new line through `o`, `O`, or `<ret>`, to determine
