aquaknight,
The CTRL+` Alternates between displaying cell values and displaying formulas in the worksheet.
This can NOT be applied to specific cells, it can only be turned on or off for the entire worksheet.
The dates are not turning into random numbers. They are being displayed as the original date serial number. Refer to MS Help extract below.
About dates and date systems
Microsoft Excel stores dates as sequential numbers which are called serial values. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,448 days after January 1, 1900. Excel stores times as decimal fractions because time is considered a portion of a day.
Because dates and times are values, they can be added, subtracted, and included in other calculations. You can view a date as a serial value and a time as a decimal fraction by changing the format of the cell that contains the date or time to General format.
Because the rules that govern the way that any calculation program interprets dates are complex, you should be as specific as possible about dates whenever you enter them. This will produce the highest level of accuracy in your date calculations.
I think I understand what you want to do, but I am not sure there is a way to do it from a worksheet formula perspective.
Why do you want to see the formula only for a specific range of cells and not all cells?
Maybe there is a different way to solve your problem other than displaying certain fomulas.
