window or unzoom (restored to the normal layout) if it already zoomed, bound to C-b z by default. The pane is unzoomed on pretty much any excuse whatsoever. We considered making this a new layout but the requirements are quite different from layouts so decided it is better as a special case. Each current layout cell is saved, a temporary one-cell layout generated and all except the active pane set to NULL. Prompted by suggestions and scripts from several. Thanks to Aaron Jensen and Thiago Padilha for testing an earlier version.
