auto-scroll-sets

The collection of all windows displaying a given object (in any of its various views) is partitioned into auto-scroll sets. Redirecting the structural selection in a given window has the effect of scrolling all other windows of the same auto-scroll set so that the leftmost character of the new structural selection is visible.

The command auto-scroll-sets is used to change the partitioning of windows into auto-scroll sets. Suppose the command is invoked in a window displaying object o. Then the associated dialog box is initialized with a list of the names of all windows that display o.

Let w, w1, and w2 be the names of windows.

Isolate(w) extracts w from its current auto-scroll set, making it an auto-scroll set consisting only of itself.

Merge(w1,w2) combines the auto-scroll sets containing w1 and w2 into one auto-scroll set.
