What is the easiest way to detect a character in a text field?

I want to be able to detect a certain character and replace that character with another specific character.

So If I write in a text field... "zyxw" I want it to be replaced with "abcd".

I'm a newbie and don't really know where to start with this or how to go about it. If anyone has any methods of doing this, I would really appreciate it.
