Variables ​

VariableDescription

selectNodeBackward

Selects the node before the cursor when at the start of a textblock.

This command provides fallback behavior for the Backspace key when structural deletion isn't possible. When the cursor is at the start of a textblock and normal backward joining fails, this command selects the node before the textblock (if it's selectable), allowing the user to delete it with a subsequent keypress.

This is particularly useful for:

  • Selecting and deleting block nodes (images, horizontal rules, etc.)
  • Handling cases where the schema prevents normal joining
  • Providing consistent behavior for navigating/selecting backward

The command only works when:

  • The selection is empty (just a cursor)
  • The cursor is at the start of a textblock (or not in a textblock)
  • There's a selectable node before the cursor

Param

The current editor state

Param

Optional dispatch function to execute the transaction

Param

Optional editor view for accurate cursor position detection

Example

typescript
// Use as fallback in Backspace handling
const keymap = {
  Backspace: chainCommands(deleteSelection, joinBackward, selectNodeBackward),
};
