4.1 Find and Replace

The find and replace function of STGuru is powerful. There is a 2-in-1 find/replace dialog box for the source and replace edit area independently. When you check on the "Enable Replace" checkbox, it will be a Find and Replace dialog box where you can replace what you hope to replace. If you check off this check box, you can find text in a safe way, and prevent the possible accident in replacing some text out of your will.
