Rows above and columns to the left of the selected cell
are indicated by dark lines that divide the display into
panes. When you scroll up and down, column labels
appear on each page and when you scroll left and right,
row labels appear on each page.
If you select a cell in column A or row 1 before you
choose Set Titles, the display is divided into only two
panes and scrolling is impacted in only one dimension.
