Use the Replace command to replace one string of text with another in the active window. When you issue the Replace command, you will see the following dialog box:

Enter the name of the text you want to replace in the Find what box. Enter the text you want to replace the old text with in the Replace with box. Clicking the Find Next button will cause LINGO to find the next occurrence of the old text. Clicking the Replace button will cause the next occurrence of the old text to be replaced by the new text. The Replace All button will replace all occurrences of the old text with the new text throughout the entire document.

Check the Match whole word only box to have LINGO replace only whole words of the text (i.e., don't replace occurrences of the text embedded in other words). Check the Match case box to have LINGO replace only instances of the text with the same capitalization.
