   Choosing the Artboard tool (Shift+O, its toolbar button, Edit Artboards in Properties or Document Setup, or the Artboards panel menu's Artboard Options…) starts it on the active artboard: the canvas outlines that artboard, and Delete, Cut, Copy, the Transform panel and Artboard Options act on it.
   Object › Artboards › Fit to Artwork Bounds and Fit to Selected Art resize the active artboard, as the Artboards panel menu's Fit to Artwork Bounds does (`artboard.fitToArt {index}`, `artboard.fitToSelection {index}`). They used to resize artboard 1 whichever artboard was active. When an action plays, its Fit to Artwork Bounds and Fit to Selected Art steps that name no artboard resize the artboard that is active then.
   The canvas draws the active artboard's edge in black, as the public [Select artboards](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/add-edit-artboards/select-artboards.html) page describes. It draws the other artboards' edges in gray. With several artboards selected by the Artboard tool, the canvas draws the black edge around the active one, which the tool shows with handles and its name. It used to draw artboard 1's edge in black whichever artboard was active.
-  View › Rotate View turns the view to the status bar's preset angles (`view.rotate {angle}`, which takes any angle).
+  View › Rotate View turns the view to the status bar's preset angles (`view.rotate {angle}`, which takes any angle). View › Rotate View to Selection turns the view to the angle of the selected objects' bounding box, so the box is square to the window (`view.rotateToSelection`).
   When the view angle changes (a Rotate View drag, the status bar's angle menu, Reset Rotate View or a saved view) and the desktop app renders the frame at the new angle on the render worker, the canvas draws the last frame turned to the new angle until that frame is ready. It used to draw no art until then.
   With the view rotated, a second Escape less than a second after the first resets the rotation, as Reset Rotate View does. The first Escape may end something else, such as isolation mode or a path being drawn. The second resets the view only when it has nothing else to end, and an Escape that closes a menu does not count. After a click, or a press of another key that is not a modifier (Shift, Control, Alt/Option or Command), the next Escape counts as the first. With the Rotate View tool chosen, one Escape resets the view.
   The status bar navigator's field shows the active artboard's number and name, and its drop-down lists every artboard by number and name, as the Artboards panel does. Choosing an artboard in the list makes it the active artboard and fits it in the window (`view.goToArtboard`). The list opens on the active artboard's row and lays out only the rows in view and at most one more.
