Thanks for replying Stanoc.
My step 5 should have read “zoom out and move bars 4 through 7 one page left leaving bar 7 empty”.
So you see with your suggestion is I would overwrite the contents of page 7 which I don’t move out of the way until step 5.
Also, I know that the clipboard is preserved after step 3 because I test that in step 4.
My guess is that the memory used to keep the copied page is cleared and reused at step 5 when I move bars 4 through 6 to the left. This is unfortunate as there are many obvious scenarios where one wants to move steps left and right in preparation for pasting something copied earlier.
