The Replace All Complete window opens after the completion of a search that was initiated by clicking Replace All on the Replace tab in the Find and Replace window. It indicates the number of replacements that were made.

If you select Do not show this message again, the Replace All Complete window does not open when subsequent searches are performed for replacing all occurrences of the specified text string. When this window does not open, a message indicating the number of replaced occurrences is shown in the left corner of the status bar. For more information, see Status Bar.

In the Options window, General > Show Replace All complete message controls whether the Replace All Complete window opens. If you select Do not show this message again in the Replace All Complete window, this checkbox in the Options window is cleared. To have the Replace All Complete window open once again, you must select this checkbox. For more information, see General User Options.
