<* PRAGMA LL *> <* PRAGMA SUBTYPE *>A
ZGrowVBTis a switch that has the side effect of reshaping its nearest ancestor subwindow.
If the initial mouse click is unshifted, the subwindow is lifted to the top of its sibling; otherwise, the subwindow keeps its current top-to-bottom ordering among its siblings. As the mouse is moved, the cursor changes to give appropriate feedback, and an outline of the subwindow is displayed to show the shape the subwindow will acquire on an uncancelled upclick. The shape of the subwindow is not actually changed until the uncancelled upclick. The outline is removed on an uncancelled upclick or on a chord-cancel.
