Jason,

Enter -1 in some cell. Copy that cell. Then select the cells whose signs
you want to change. Then go to the Edit menu Choose Paste Special, and
choose the Multiply option.

Does anyone have a macro written that will change the sign
(from positive to negative or negative to positive) of a
number in a cell in excel? Or, does MSFT already have a
keyboard shortcut for this operation? Please help.
