375−| `enable` | If set to true, then when the cursor is in a position with non-whitespace to its left, instead of inserting a tab, it will run `move_parent_node_end`. If there is only whitespace to the left, then it inserts a tab as normal. With the default bindings, to explicitly insert a tab character, press Shift-tab. | `true` |
376−| `supersede-menu` | Normally, when a menu is on screen, such as when auto complete is triggered, the tab key is bound to cycling through the items. This means when menus are on screen, one cannot use the tab key to trigger the `smart-tab` command. If this option is set to true, the `smart-tab` command always takes precedence, which means one cannot use the tab key to cycle through menu items. One of the other bindings must be used instead, such as arrow keys or `C-n`/`C-p`. | `false` |

3−Helix uses tree-sitter to correctly indent new lines. This requires a tree-
4−sitter grammar and an `indent.scm` query file placed in `runtime/queries/
5−{language}/indents.scm`. The indentation for a line is calculated by traversing
6−the syntax tree from the lowest node at the beginning of the new line (see
7−[Indent queries](#indent-queries)). Each of these nodes contributes to the total
8−indent when it is captured by the query (in what way depends on the name of

15−By default, Helix uses the `hybrid` indentation heuristic. This means that
16−indent queries are not used to compute the expected absolute indentation of a
17−line but rather the expected difference in indentation between the new and an
18−already existing line. This difference is then added to the actual indentation
19−of the already existing line. Since this makes errors in the indent queries
20−harder to find, it is recommended to disable it when testing via

26−When Helix is inserting a new line through `o`, `O`, or `<ret>`, to determine
27−the indent level for the new line, the query in `indents.scm` is run on the
28−document. The starting position of the query is the end of the line above where
29−a new line will be inserted.
30−
31−For `o`, the inserted line is the line below the cursor, so that starting
32−position of the query is the end of the current line.

65−their [capture types](#capture-types) and [scopes](#scopes) to a final indent
66−level for the line.
67−
68−### Capture types
69−
70−- `@indent` (default scope `tail`):
71− Increase the indent level by 1. Multiple occurrences in the same line *do not*
72− stack. If there is at least one `@indent` and one `@outdent` capture on the
73− same line, the indent level isn't changed at all.
74−- `@outdent` (default scope `all`):
75− Decrease the indent level by 1. The same rules as for `@indent` apply.
76−- `@indent.always` (default scope `tail`):
77− Increase the indent level by 1. Multiple occurrences on the same line *do*
78− stack. The final indent level is `@indent.always` – `@outdent.always`. If
79− an `@indent` and an `@indent.always` are on the same line, the `@indent` is
80− ignored.
81−- `@outdent.always` (default scope `all`):
82− Decrease the indent level by 1. The same rules as for `@indent.always` apply.
83−- `@align` (default scope `all`):
84− Align everything inside this node to some anchor. The anchor is given
85− by the start of the node captured by `@anchor` in the same pattern.
86− Every pattern with an `@align` should contain exactly one `@anchor`.
87− Indent (and outdent) for nodes below (in terms of their starting line)
88− the `@align` node is added to the indentation required for alignment.
89−- `@extend`:
90− Extend the range of this node to the end of the line and to lines that are
91− indented more than the line that this node starts on. This is useful for
92− languages like Python, where for the purpose of indentation some nodes (like
93− functions or classes) should also contain indented lines that follow them.
94−- `@extend.prevent-once`:
95− Prevents the first extension of an ancestor of this node. For example, in Python
96− a return expression always ends the block that it is in. Note that this only
97− stops the extension of the next `@extend` capture. If multiple ancestors are
98− captured, only the extension of the innermost one is prevented. All other
99− ancestors are unaffected (regardless of whether the innermost ancestor would
100− actually have been extended).
101−
102−#### `@indent` / `@outdent`
103−
104−Consider this example:

124−```scm
125−((block) @indent)
126−["}" ")"] @outdent
127−```
128−
129−Note how on the second line, we have two blocks begin on the same line. In this
130−case, since both captures occur on the same line, they are combined and only
131−result in a net increase of 1. Also note that the closing `}`s are part of the
132−`@indent` captures, but the 3 `@outdent`s also combine into 1 and result in that
133−line losing one indent level.
134−

172−of this, it will miss the entire function node and its indent capture, leading
173−to an indent level one too small.
174−
175−To address this case, `@extend` tells helix to "extend" the captured node's span
176−to the line feed and every consecutive line that has a greater indent level than
177−the line of the node.

17+Added indents don't always apply to the whole node. For example, in most
18+cases when a node should be indented, we actually only want everything
19+except for its first line to be indented. For this, there are several
20+scopes (more scopes may be added in the future if required):
23121
232−In Python, the are a few tokens that will always end a scope, such as a return
233−statement. Since the scope ends, so should the indent level. But because the
234−function span is extended to every line with a greater indent level, a new line
235−would just continue on the same level. And an `@outdent` would not help us here
236−either, since it would cause everything in the parentheses to become outdented
237−as well.
22+- `all`:
23+This scope applies to the whole captured node. This is only different from
24+`tail` when the captured node is the first node on its line.
23825
239−To help, we need to signal an end to the extension. We can do this with
240−`@extend.prevent-once`.
26+- `tail`:
27+This scope applies to everything except for the first line of the
28+captured node.
24129
30+Every capture type has a default scope which should do the right thing
31+in most situations. When a different scope is required, this can be
32+changed by using a `#set!` declaration anywhere in the pattern:

255−As mentioned before, normally if there is more than one `@indent` or `@outdent`
256−capture on the same line, they are combined.
39+## Capture types
25740
258−Sometimes, there are cases when you may want to ensure that every indent capture
259−is additive, regardless of how many occur on the same line. Consider this
260−example in YAML.
41+- `@indent` (default scope `tail`):
42+Increase the indent level by 1. Multiple occurrences in the same line
43+don't stack. If there is at least one `@indent` and one `@outdent`
44+capture on the same line, the indent level isn't changed at all.

271− bar: baz
272− xyzzy: thud
273− fred: plugh
274−```
46+- `@outdent` (default scope `all`):
47+Decrease the indent level by 1. The same rules as for `@indent` apply.
27548
276−In YAML, you often have lists of maps. In these cases, the syntax is such that
277−the list element and the map both start on the same line. But we really do want
278−to start an indentation for each of these so that subsequent keys in the map
279−hang over the list and align properly. This is where `@indent.always` helps.
49+- `@extend`:
50+Extend the range of this node to the end of the line and to lines that
51+are indented more than the line that this node starts on. This is useful
52+for languages like Python, where for the purpose of indentation some nodes
53+(like functions or classes) should also contain indented lines that follow them.

57+a return expression always ends the block that it is in. Note that this only stops the
58+extension of the next `@extend` capture. If multiple ancestors are captured,
59+only the extension of the innermost one is prevented. All other ancestors are unaffected

52−### Special registers
49+The system clipboard is not directly supported by a special register. Instead, special commands and keybindings are provided. Refer to the
50+[key map](keymap.md#space-mode) for more details.

54−Some registers have special behavior when read from and written to.
55−
56−| Register character | When read | When written |
57−| --- | --- | --- |
58−| `_` | No values are returned | All values are discarded |
59−| `#` | Selection indices (first selection is `1`, second is `2`, etc.) | This register is not writable |
60−| `.` | Contents of the current selections | This register is not writable |
61−| `%` | Name of the current file | This register is not writable |
62−| `+` | Reads from the system clipboard | Joins and yanks to the system clipboard |
63−| `*` | Reads from the primary clipboard | Joins and yanks to the primary clipboard |
64−
65−When yanking multiple selections to the clipboard registers, the selections
66−are joined with newlines. Pasting from these registers will paste multiple
67−selections if the clipboard was last yanked to by the Helix session. Otherwise
68−the clipboard contents are pasted as one selection.
52+The black hole register is a no-op register, meaning that no data will be read or written to it.
