Tooltip for macro button in a worksheet
 

Dear All,
How do we Make a tooltip appear when mouse is moved over a object in a
worksheet (similar as the comments appear when we move mouse over that
cell).
I normally place a object like 'smiley' on a worksheet and assign a
macro to that. What I want is to display some text when I Move my
mouse over it so that I will know which macro is assigned to it
without actually rightclicking and seeing the assign macro option
Hope I explained sufficient.
Thanks
