VBA & Macros code : I'm trying to get into VBA for the first time in order to be more productive at work. Now I'm starting with something simple, here it goes. I changed the color and other things of a specific cell in a worksheet ("M1" cell), but I need to do the same thing in all the next worksheets of my workbook (is the same cell in all the sheets), but there are too many sheets (about 40), so I need to programming this task with VBA, how can I do that?. 
First attempt - When I changed the look of the cell I recorded the procedure in a macro, but don't know how to write the right code in order to do this in all the worksheets.
