- Default: `'paragraphs'`

How text is grouped into editable blocks. **Keep the default, `'paragraphs'`**: it is what Edit Text is built around. It makes one block per paragraph: the consecutive lines of one column that share leading and face are selected, moved and edited together, while columns, bullets, headings, table rows and lone numbers stay apart; a tagged document's own paragraph elements settle the grouping where it has them. Typing inside a paragraph reflows it within its box: words flow onto the next line and back, Enter starts a new line, every word keeps its own font, size and color, and a changed line keeps the paragraph's alignment, justified spacing included.

`'rows'` is an alternative, not an improvement: it makes one block per visual row, split where a gap reads as a column boundary, so each line of a paragraph is its own block and is selected, moved and edited on its own.

- `'paragraphs'`: Default, and recommended. One block per paragraph; typing reflows the paragraph within its box.
- `'rows'`: One block per visual row, split where a gap reads as a column boundary; a paragraph's lines are edited one at a time.
