+## Character Direction
+
+`text.setFormat {charDirection: "default"|"leftToRight"|"rightToLeft"}` (the selected type, or `ids`) and
+`text.setRangeStyle {id, start, end, charDirection}` (a range) set the direction of the characters inside their
+paragraph, as the Character panel menu's Character Direction does with the Middle Eastern (Indic) options shown. The bidi
+algorithm (UAX #9) resolves each stretch of characters with a direction as an embedding in that direction, as if an LRE
+or RLE stood before it and a PDF after it: `leftToRight` keeps a date written with spaces, such as `21 10 2026`, in its
+order inside a right-to-left paragraph, and `rightToLeft` sets a Hebrew or Arabic word and the punctuation after it right
+to left inside a left-to-right paragraph. Characters keep their own strong direction inside an embedding: Latin letters
+set Right to Left still read left to right. `default` leaves the characters to the bidi algorithm. The paragraph's own
+direction is unchanged. SVG export writes type with a character drawn right to left, or with a run set Right to Left,
+as outlines; live SVG text writes `direction="ltr"` and `unicode-bidi="embed"` on each run set Left to Right. Character
+Direction is Default until set and is saved only when set, and character styles captured from type carry it. Each
+command is one undo step.

   Optical Margin Alignment and Roman Hanging Punctuation hang right-to-left paragraphs of point and area type, and type on a path whose first paragraph runs right to left, too. Auto aligns a right-to-left line at its right, or at the end bracket of a path, so it hangs there. A right-to-left line is read from right to left: where it hangs at its left margin, `."` ending it hangs both glyphs.
   The Paragraph panel menu's Hyphenation… (`ui.hyphenation`, `text.setFormat {wordsLongerThan, afterFirst, beforeLast, hyphenLimit, hyphenationZone, hyphenateCapitalized}`) sets each paragraph's hyphenation limits: the shortest word that breaks, the fewest letters on each side of the hyphen, the most hyphenated lines in a row, a zone at the right edge where the Single-line Composer breaks before a word instead of hyphenating it, and whether capitalized words break. The defaults are words longer than 5 letters, 3 letters on each side, no limit or zone, and capitalized words hyphenated; paragraph styles and the native file keep the options.
   The Paragraph panel's Insert Kashidas (with the Indic options; `text.setFormat {kashida}`) lengthens each Arabic word of a justified horizontal area type line with a kashida, a tatweel between its last pair of joined letters, before the word spaces widen: Short, Medium and Long kashidas are at most a quarter, half and a whole em long, Stylistic ones are whole tatweels up to an em, and None (the default) leaves the line as before; paragraph styles and the native file keep the setting.
+  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`).
   With Snap to Unit off and Shift not held, a tab stop placed by a click on the Tabs panel's ruler or dragged on it lands on the nearest whole point. A position typed in the X or Y field keeps its hundredths of a point.
