Steve lived on for quite some time in an undocumented key command you could use in the Finder. I forget the exact sequence; ctl-alt-cmd-shift space or something. It has become more broken over releases and may be gone now. We added it to make all animations go very slow. We would invoke it at Steve’s request in demo to him and he would open and close windows, show and hide sidebars, enter and exit TimeMachine and more. This shipped in numerous version of OSX.
