+    Direct Selection's marquee selects the frame anchors of area type that lie inside it, and a click on a frame anchor selects that one; Shift toggles them. The selected frame anchors show filled. A drag of one of them moves all of them, the arrow keys nudge them, and the type reflows at its size (`text.reshapeArea`, which takes `items` to move the anchors of several frames in one step), as [Create text](http://web.archive.org/web/20220127090642/https://helpx.adobe.com/illustrator/using/creating-text.html) and [Selecting objects](http://web.archive.org/web/20211230015528/https://helpx.adobe.com/illustrator/using/selecting-objects.html) describe. When the selection also holds other objects, path anchors or ruler guides, or when another change to the document or the selection follows the pick, the type is selected whole.
   - **Group Selection (#2441):** a click picks one path of a compound path (its outline within the pick tolerance, else the innermost path whose area holds the click: the outer shape or a hole), Shift-click adds another, and a click on a selected path adds the compound path, as a click on a group member climbs to its group. A path selected this way moves, rotates and scales on its own; paint still goes to the compound path.
     With Direct Selection, an Alt-click on a path selected whole adds its group, and each further Alt-click adds the next group up, as Group Selection's clicks do; the climb stops below the layer and its sublayers and at the isolated object. An Alt-drag still copies the selection, and Alt+Shift-click on a segment or the fill still adds or removes the path.

     With Direct Selection, Shift pressed during the drag of a curved segment keeps both of its handles at right angles to the line between its anchors, on the same side and at the same length (`path.reshapeSegment {perpendicular}`). Shift held while any segment is dragged with the Anchor Point tool or the Pen with Alt does the same. With the Anchor Point tool, Shift held at the press on an anchor (or a selected blend's spine point) moves it, handles and all, instead of pulling out handles; Shift kept down keeps the move at 45° steps, and a Shift-click that doesn't move leaves the anchor as it was (`path.moveAnchor`). A selected blend spine's segment dragged with the Anchor Point tool, or a curved one dragged with Direct Selection, bends the same way (`object.blend.spine.reshapeSegment`).
