Is there a way to enter a letter in a letter in a cell and once the
Enter key is struck, the letter will change to become a symbol that is
located in another cell? More specifically:

1) I have multiple ranges where I usually enter an "x". The ranges
are A1:C10 and A20:C30.

2) There is a symbol in Z1.

When I enter the "x" in multiples places within my ranges, I want the
"x" (or any other letter that might be entered) to instantly change to
the symbol when I stike the Enter key. Is this possible? Thanks for
any help you may offer.
