Variable Description

Variable	Description
joinListItemBackward	Handles backspace at the start of the first paragraph of a list item when the previous sibling list item also ends with a paragraph. In the default `joinBackward` behaviour, pressing backspace at the start of item 2 in: `• Hello • World ← cursor at start` merges the two list items, producing a single list item with two paragraphs: `• Hello World` This command goes one step further and also merges the two paragraphs, inserting a single space between the text content so the result is: `• Hello World ← cursor placed after the inserted space` The command is intentionally narrow: it only fires when the cursor is at the very start of a textblock, that textblock is the first child of its parent node (the list item), the list item is not the first child of its own parent (a previous sibling exists), the previous sibling list item's last child is also a textblock (so the merge is content-compatible). All other cursor positions fall through to the normal `joinBackward` / `selectNodeBackward` commands, so existing behaviour is fully preserved. Param The current editor state. Param Optional dispatch function to execute the transaction. Param Optional editor view for bidirectional-text detection.

Handles backspace at the start of the first paragraph of a list item when the previous sibling list item also ends with a paragraph.

In the default joinBackward behaviour, pressing backspace at the start of item 2 in:

• Hello
• World   ← cursor at start

merges the two list items, producing a single list item with two paragraphs:

• Hello
  World

This command goes one step further and also merges the two paragraphs, inserting a single space between the text content so the result is:

• Hello World   ← cursor placed after the inserted space

The command is intentionally narrow: it only fires when

the cursor is at the very start of a textblock,
that textblock is the first child of its parent node (the list item),
the list item is not the first child of its own parent (a previous sibling exists),
the previous sibling list item's last child is also a textblock (so the merge is content-compatible).

All other cursor positions fall through to the normal joinBackward / selectNodeBackward commands, so existing behaviour is fully preserved.

Param

The current editor state.

Param

Optional dispatch function to execute the transaction.

Param

Optional editor view for bidirectional-text detection.
