   With Align to Artboard chosen, the Align panel's Distribute Objects and Distribute Spacing buttons use the active artboard (`object.distribute` and `object.distributeSpacing` with `to: "artboard"` and `artboard`). The first object's left or top edge goes to the artboard's left or top edge, and the last object's right or bottom edge goes to the artboard's right or bottom edge. Distribute Objects spaces the other objects evenly by its button's line, and two objects are enough. Distribute Spacing makes the gaps between the objects equal. With anchor points selected, the buttons space the points among themselves and do not use the artboard. When an action plays, its Distribute Objects and Distribute Spacing steps with Align to Artboard use the artboard that is active then.
   With a key object, the Align panel's Distribute Objects buttons use the Distribute Spacing value (`object.distribute {spacing}`): the key object, or the compound path or selected group that contains it, stays in place, and the objects' left edges, centers or right edges (top edges, centers or bottom edges) end up that far apart, outward from the key object's, in their order. With the field's default value of 0, a click puts every object on the key object's line (behavior reference: [Ask Mordy: Distributing Objects](http://rwillustrator.blogspot.com/2008/01/ask-mordy-distribute.html)).
   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 the Artboards panel menu's Fit to Artwork Bounds fit each selected artboard (those the Artboard tool has selected, else the active one) to the art on it, as the public [Use the artboard context menu](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/organize-manage-artboards/use-artboard-context-menu.html) page describes (`artboard.fitToArt {indices}`). An object partly on an artboard counts for each artboard it overlaps, and an artboard with no art on it keeps its size and place. They used to fit the active artboard to all the art in the document.
+  A Fit to Artwork Bounds step of a batch run from the app (`command.batch`), including an action played from the Actions panel, fits each artboard the Artboard tool has selected when the step runs, as the command does on its own and as the [help page](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/organize-manage-artboards/use-artboard-context-menu.html) describes. A step's own `index` or `indices` is kept, and the journal records the artboards the step fitted, so a replay fits the same ones. The step used to fit only the active artboard.
   The Artboards panel menu's Duplicate Artboards copies each selected artboard (those the Artboard tool has selected, else the active one) with its art, in one undo step, and the copies are then selected, as the public [Use the artboard context menu](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/organize-manage-artboards/use-artboard-context-menu.html) page describes. With the Artboard tool, Copy and Cut take every selected artboard with its art, as the public [Cut, copy, and paste artboards](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/organize-manage-artboards/cut-copy-and-paste-artboards.html) page describes, and Paste brings them all back in one undo step (`artboard.duplicate`, `artboard.copy` and `artboard.cut` with `indices`). The copies keep their places relative to each other, together right of the last artboard. All three used to act on the active artboard only.
   With the Artboard tool selecting several artboards, Paste in Place, Paste in Front and Paste in Back put a copy of the copied art on each, where it was on the artboard it was copied from, in one undo step, as the public [Cut, copy, and paste artboards](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/organize-manage-artboards/cut-copy-and-paste-artboards.html) page describes (`artboards` on the three commands). Art copied from no artboard keeps its place on the first selected artboard and its offset to it on the others, and an `artboard` or `artboards` index the document does not have is an error; these rules are VectorCraft's own. The three commands used to paste one copy, on the active artboard, and an `artboard` index the document did not have pasted the art where it was.
   A replay of the journal repeats a Cut or Copy made with the Artboard tool on the artboards it took (`edit.cut` and `edit.copy` record `selectedArtboards` and `art`), whichever tool is chosen in the new session and whatever is selected there. A recorded action follows the tool chosen when it plays. The replay used to act on the objects selected then, or stop with nothing selected. This rule is VectorCraft's own.
