   The Paragraph panel's Numbered List button, Type › Bullets and Numbering › Apply Numbers and the context menu's Apply Numbers (`text.setFormat {list, number}`, `type.applyNumbers`) make paragraphs a numbered list with the documented presets (1, A, a, I, i, 01, 001, and None, which turns the list off; [Bullets and numbering](https://web.archive.org/web/20250807202418/https://helpx.adobe.com/illustrator/using/bullets-numbering.html), [Create bulleted or numbered lists](https://web.archive.org/web/20260417034638/https://helpx.adobe.com/illustrator/desktop/design-with-text/edit-format-text/create-bulleted-or-numbered-lists.html)): each paragraph starts with its number and a period, counted through the list paragraphs of the story and its threaded frames, with the text and indents as in a bulleted list; letters go on from Z to AA, and roman numerals go on from III to IV, an empty paragraph is not numbered, and a paragraph in no list starts the count again at 1.
   Type › Bullets and Numbering › Convert to Text (`type.convertListToText`, `text.convertListToText`) makes the bullets and numbers of the list paragraphs editable characters of their text ([Create bulleted or numbered lists](https://web.archive.org/web/20260417034638/https://helpx.adobe.com/illustrator/desktop/design-with-text/edit-format-text/create-bulleted-or-numbered-lists.html), [December 2022 release notes](https://web.archive.org/web/20260203094741/https://helpx.adobe.com/illustrator/using/whats-new/2023-1.html)): each marker becomes its characters and a tab at the start of its paragraph, in the marker's font, size and color, the list is turned off, and a left tab stop at the left indent keeps the text after the tab where it started; threaded type keeps the numbers its story counted.
   The Type tool starts a list from the characters [Create bulleted or numbered lists](https://web.archive.org/web/20260417034638/https://helpx.adobe.com/illustrator/desktop/design-with-text/edit-format-text/create-bulleted-or-numbered-lists.html) names (`text.startList`): a space typed on its own after `1.`, `1)`, `A.` or `A)` at the start of a paragraph in no list makes the paragraph a numbered list in 1, 2, 3 or A, B, C, and a space typed after `*`, `#`, `>` or `+` makes it a bulleted list with the filled dot. The typed characters are removed, and one Undo puts them back as text with no list. The same characters later in a paragraph, and pasted list characters, start nothing.
+  PDF export writes bullets and numbers as text, in the glyphs and at the places the canvas draws them, in area type, type on a path, right-to-left paragraphs and threaded frames, and a PDF viewer selects, copies and finds them; a marker glyph that stands for no character is drawn as a path.
   The Character panel menu's Character Direction (with the Indic options; `text.setFormat {charDirection}`, `text.setRangeStyle {charDirection}`) sets the selected characters left to right or right to left inside their paragraph, as a Unicode bidi embedding: a date set Left to Right keeps its order in right-to-left text, and a word set Right to Left keeps the punctuation after it on its left. Default (the default) leaves the characters to the bidi algorithm; character styles and the native file keep the setting.
   In vertical type, the Tabs panel names its alignment buttons Top-Justified Tab, Center-Justified Tab, Bottom-Justified Tab and Decimal-Justified Tab, in their tool tips and for screen readers, and labels the position field Y. In horizontal type the buttons keep the names Left-Justified Tab and Right-Justified Tab, and the field keeps the label X.
   The Tabs panel's ruler is numbered in the General unit with the canvas rulers' label steps and a tick every tenth of a step. With the panel menu's Snap to Unit on, or Shift held, a tab stop placed by a click on the ruler or dragged on it lands on the nearest tick (`text.tabs.set`).
