You can find and change any text in any field. This is called "doing a Find-and-Change". To do this, you must first choose "Find", Cmd-F, and type the old text you want to find, and the new text you want to change, in the "Find What" and "Change To" text boxes. When you click "Find", Dynodex will go to the first place it finds the old text. If you want to change the old text to the new text, here is where you choose "Change", Cmd-H.
