   The Tabs panel menu's Clear All Tabs (`text.tabs.clear`), Delete Tab and Repeat Tab (`text.tabs.set`) can be chosen while the panel's ruler shows tab stops. Delete Tab removes the stop selected on the ruler. Repeat Tab replaces the stops after the selected stop with up to 20 copies of it. The copies are spaced by the selected stop's distance from the stop before it, or from the paragraph's left indent when it is the first stop, and no copy is placed at 2,000 pt or beyond. Clear All Tabs removes every stop, so the default stops every ½ inch apply again.
 - **Interface languages, vertical type:** Preferences ▸ User Interface (or VectorCraft ▸ Language on macOS) picks Automatic (the system locale) or a registered language, persisted as `interfaceLanguage`. Translations come from per-language catalogs (`i18n/*.tsv`): Traditional and Simplified Chinese, Japanese, German (every `de-*` locale), Spanish (neutral international Spanish, for every `es-*` locale), French (every `fr-*` locale), Italian (every `it-*` locale), Russian (every `ru-*` locale) and Ukrainian (every `uk-*` locale), Catalan (every `ca-*` locale) and Polish (every `pl-*` locale; AI-drafted, native review pending) cover the whole interface, Czech every menu label; Czech, German, Greek, Spanish, French, Hungarian, Italian, Japanese, Korean, Vietnamese, Polish, Brazilian Portuguese, Russian, Simplified Chinese, Traditional Chinese, Swedish, Ukrainian and Finnish also translate status-bar and error messages as they are shown (`@msg` templates, every message literal tested; the messages themselves stay English for agents); untranslated text stays English. Japanese and Chinese glyphs come from the craft-fonts build input (release builds) or the installed fonts, Czech, German, Spanish, French, Italian, Russian and Ukrainian ones from the bundled UI fonts. The web app follows the browser's languages (or `?lang=`). The Basic toolbar's Type button holds Vertical Type in its flyout. Vertical Type, Vertical Area Type and Vertical Type on a Path create vertical text (columns right to left, upright CJK glyphs and marks with `vert` alternates, Latin and longer numbers on their side, two- and three-digit numbers set as tate-chu-yoko in one em of the column (kept whole when justified), upright glyphs centred on the column (tracked or justified too), point type's anchor on the first column's centre line); kinsoku applies to horizontal and vertical Japanese (Paragraph panel › Kinsoku Set, `text.setFormat {kinsoku}`: Hard, the default, keeps closing marks, iteration marks, the prolonged sound mark and small kana off the line start and opening brackets off its end; Soft lets 々, ー and small kana start a line as JLREQ's level 3 rules do; None turns it off), and justified Japanese lines spread their room between characters (not inside Latin words); Paragraph panel › Mojikumi Set (shown with Preferences › Type › Show East Asian Options, `text.setFormat {mojikumi}`): None or Line-end Punctuation Half Width (new type's default, as in Illustrator; older documents and imported text keep None) shares one half-em space between consecutive punctuation, sets a closing mark ending a line half width and an opening bracket starting a line flush with its start (a paragraph's first line at its first-line indent, JIS X 4051's principle in JLREQ 3.1.5), and puts a quarter em between Japanese and Latin letters or digits; Paragraph panel menu › Top-to-Top / Bottom-to-Bottom Leading measures leading from em box top to top (area type's first line touches the frame) or from baseline to baseline (new type in a Japanese interface starts top to top, with em box centre character alignment, #432); Paragraph panel menu › Burasagari None / Regular / Force (`text.setFormat {burasagari: "none"|"standard"|"forced"}`) hangs an East Asian comma or full stop (、。，．､｡) ending an area type line outside it, Regular (new type's default) when it doesn't fit and Force always (the rest of the line then fills the measure; closing brackets and Latin punctuation don't hang); Character panel menu › Character Alignment (with the East Asian options; `text.setFormat` or `text.setRangeStyle {charAlign}`) lines characters smaller than the largest on their line up on the Roman baseline, the em box top/right, centre or bottom/left, or the ICF (ideographic character face) top/right or bottom/left, from the font's BASE table or, without one, the average ink box of some ideographs and kana; Proportional Metrics (the same menu; `{proportionalMetrics}`) sets full-width glyphs on the font's proportional widths (OpenType `palt`) in horizontal type and upright glyphs on its proportional heights (`vpal`, shaped top to bottom; fonts without vertical metrics keep their cells) in vertical type, and Line-end Punctuation Half Width takes nothing more off the punctuation they re-spaced; Type ▸ Type Orientation switches existing text; caret, selection, hit testing and arrow keys follow the writing direction. Vertical text exports to PDF as real text and to SVG as outlines. The interface is available in Polish (`pl`): menus, panels, dialogs and messages, with one/few/many plurals; AI-drafted, native review pending (#1498).
   Character panel menu › Standard Vertical Roman Alignment (with the East Asian options; `text.setFormat` or `text.setRangeStyle {standardVerticalRoman}`, off by default) stands the selected Latin letters, digits and other half-width characters upright one below the other in vertical type instead of rotating them ([formatting Asian characters](https://helpx.adobe.com/illustrator/using/formatting-asian-characters.html)); spaces keep their width, tate-chu-yoko blocks stay across the column, and Character Style Options gives it its own checkbox beside Character Alignment.
+  The Character panel's All Caps, Underline and Strikethrough buttons and its menu's All Caps, Underline, Strikethrough, Proportional Metrics, Tate-chu-yoko and No Break show off while only some of the selected characters have the attribute, and choosing one then turns it on for all of them, as `type.underline` (Cmd+Shift+U) does for underlining; the Character Alignment and Digits submenus check no item while the selected characters differ. `text.setFormat` refuses a value that is not true or false for its on/off attributes, as `text.setRangeStyle` does.
 - **Transparency:** opacity masks (clip/invert/disable/link), exported as SVG `<mask>` and PDF soft masks. The constant alpha soft mask that PDF and `.ai` export draw a CMYK page with transparency through is white, so applications that read every soft mask by its luminosity show the page too (#1359, part of #1286).
   Isolation mode and opacity mask editing exclude each other ([transparency and blending modes](https://web.archive.org/web/20230102045151/https://helpx.adobe.com/illustrator/using/transparency-blending-modes.html)): in isolation mode a click or Alt-click on the mask thumbnail does not edit the mask, and Make Mask is off for one object; while a mask is edited, Enter Isolation Mode and Object › Perspective › Edit Text are off, the Contextual Task Bar leaves out Isolate, and Quick Actions leave out Isolate Group.
   Pattern editing mode and opacity mask editing exclude each other, by a rule of VectorCraft itself: in pattern editing mode a click or Alt-click on the mask thumbnail does not edit the mask, and Make Mask is off for one object; while a mask is edited, Object › Pattern › Make and Edit Pattern are off.
