I create elaborate worksheets and would like to have the cells that need
periodic updating to stand out in bold or a different font from the other
(formula-driven) cells, but I do not want them to appear differently when
printed. Has anyone developed an idea that works for this?

Also, I would like to have certain rows on my spreadsheet for information
that would never print out, but would be within my print range. Is there a
way to print without them other than to hide the rows?
