Select: Same › Link Block Series selects every frame of a text thread

Select › Same › Link Block Series (select.same.linkBlockSeries) selects every
frame of the threads that the selected type objects, and the type inside
selected groups, are in, in thread order. Type in no thread selects itself,
other selected objects are left out, and with frames of several threads
selected it selects all of them. Hidden, locked and out-of-isolation frames
are left out, Reselect repeats it, and it records no undo step. The item is
off while no type is selected.

   Type › Convert To Point Type on a frame of threaded text makes point type of the text that frame holds and takes it out of the thread; the story flows through the other frames without that text, so each character is in the document once.
   Object › Rasterize on a frame of threaded text takes it out of the thread with the text it shows, which the image draws, and the other frames keep the text they hold. When the last frame is rasterized, the text it has no room for goes after the text of the last frame that stays.

When the last frame is outlined, the text it has no room for goes after the text of the last frame that stays. When Expand Appearance keeps the frame as type in a group with its shadow, outer glow or Crop Marks, the type stays in the thread. The public help on threads ([Create text threads between objects](https://helpx.adobe.com/illustrator/desktop/design-with-text/add-manage-text/create-text-threads-between-objects.html), [Remove or break text threads between objects](https://helpx.adobe.com/illustrator/desktop/design-with-text/add-manage-text/remove-or-break-text-threads-between-objects.html)) does not describe outlining a threaded frame; this handling is VectorCraft's own behavior.

When every frame of a thread goes into the symbol, the copy of the last frame keeps all its text.
   With Optical Margin Alignment on, or Roman Hanging Punctuation on in the first paragraph, the glyphs at the ends of left-to-right type on a path hang outside its brackets, measured along the path. The type hangs at the start bracket when its line is placed there, hangs at the end bracket when the line is placed there, and hangs at both when it is centered. Glyphs that hang past the end bracket do not make the type overflow, and a hang stops at an open path's end. SVG export writes such type as outlines.
