ReadOnly

Controls the whether the user can edit the text content ($Text) of a note.

$ReadOnly does not affect other note attributes. By default new notes are editable. Besides various read-only system attributes, this attribute is normally used for notes that fetch their content from the web: you don't really want to modify their content or indeed, cannot.

When set to true, to select text in the note you must use Cmd+drag-select instead of the normal drag select.
