Creating checkable boxes w/o the check box forms tool

[crimsontodd]

Not sure if this can be done. When you use certain fax cover sheets in the
Word templates, there are boxes that can be checked and unchecked with a
double-click. It incorporates a blank-box wingding that when double-clicked
becomes a checked-box wingding. I am comfortable with how to insert the
symbols (wingding characters) but not sure how to incorporate the
double-click feature. I'm thinking it may be a macro but was hoping I could
do the same thing is Excel. The check box feature on the forms menu of Excel
is too advanced for the simple task I'm trying to accomplish. Help!
