They're called Checkboxes, and there are two types. One is found on the
Forms toolbar (go to View menu > Toolbars, and select Forms), the other on
the Controls Toolbox (View menu > Toolbars, select VBA, then click on the
button with the wrench and hammer). You can link each checkbox to a cell,
which will display TRUE or FALSE depending on whether the box is checked. I
prefer to use the Forms version, but the Controls Toolbox version offers
more formatting options.
