Select the title, but not so you get the blinking insertion point within the text of
the title: you need to have the gray selection rectangle around the title.
Now type the equals key (you'll see the equals sign in the formula bar), click on
the cell (the cell reference will appear after the equals sign in the formula bar),
and press Enter.
This works in every version of Excel since about Excel 5.
