You could use a font character for the checkmark,
some choices in http://www.mvps.org/dmcritchie/rexx/...bols.htm#ticks

Format Column A as "Wingdings 2" and use a "P" for the checkmark,
or choose a different checkmark from the above chart. Then change
row 1 or cell A1 to normal font perhaps bolded.

Right click on the spreadsheet tab, view code and place the
following event code there you can take a choice of double-click event at
http://www.mvps.org/dmcritchie/excel/event.htm#ticks.

I am trying to create a worksheet that contains a yes/no option by inserting
a check mark in a box.
