getFocusTextBlock
constgetFocusTextBlock:EditorSelector<{node:PortableTextTextBlock;path:BlockPath; } |undefined>
Defined in: selector.get-focus-text-block.ts:15
Returns the text block containing the focus selection, resolved at any depth.
When the focus is inside an editable container (e.g. a code block’s line), this returns the innermost text block ancestor (the line), not the outer container. When the focus is at root, behavior is unchanged.
