Select View->Find or press Ctrl+F to locate a string of text in the Source Window. Enter the string in the Find dialog. The debugger searches forward from the current highlighted word or line to the end of the file, then wraps to the beginning and searches up to the highlighted word or line. If the string is found, it is highlighted. Otherwise the message Text not found is displayed.
If you want to search for only exact case matches to the search string, click on the Case sensitive check box.
Once you have entered a string in the Find dialog, you can repeat the find operation by selecting View->Find Next or by pressing Ctrl+N.
