i do a lot of comparing cells. my go-to formula is "=c1=c2". Of course I
get a true if they're equal and false otherwise. If I have a lot of cells I
sometimes add conditional formatting that colors the cells false red.

Now my question...maybe I could create a custom function in my personal.xls
workbook that does the compare and the conditional formatting in a single
step. Is something like this worth pursuing?
