Search|Instant Find Next looks for the next occurrence in the current file of the word under the text cursor. When the word is found, Instant Find Next selects it. If there is no word under the text cursor, or it doesn’t occur again in the file, nothing happens at all. If some text is selected when you invoke Instant Find Next, and the selection does not span more than one line, Instant Find Next will search for the selected text rather than the word under the cursor.
The purpose of Instant Find Next and Search|Instant Find Previous is to quickly “walk” through the file, stopping at each spot where the word occurs. Since a successful match selects the word that was searched for, you can instantly search for further matches.
If Instant Incremental Search is active, then Instant Find Next finds the next occurrence of the incremental search term.
This command is intended to be used without the Search toolbar. By default, it has a button on the main toolbar. To the left of this button is the Instant Incremental Search button. It has a drop-down menu with instant search options that affect Instant Find Next.
