Re a longer post I submitted recently: Execute the following as the only (or final) contents of a notebook Do[Plot[x^k, {x,0,1}, PlotRange->{{0,1}, {0,1}}], {k,1,4}] Then Select All cells (cmd-A); Animate (cmd-Y); and hit the up or down arrow keys a few times or click the vertical bars in the control strip to pause the animation. Single-stepping the animation backward using the up/down? arrow key will now take you down to the k=1 plot, then loop back up to the k=4 plot. Single-stepping the animation forward using the down/up? arrow key will take you up to the k=4 plot, but will NOT loop back down to the k=1 plot (although the free-running animation does seem to loop around OK). Adding another cell (even a header or text cell) at the end of the notebook, however, so that there is another cell after the k=4 plot, will enable cyclic single-step looping in either direction around the loop.
