Use this command to search the currently active editor for the previous match to a specific phrase (ie, that was used with the Find command). This command is unavailable if there is no text to search, or the Find command was not previously used.

This does not present the Find dialog box. Instead, the same search parameters, that were previously used with the Find command, are used once again, except that a Direction of Up is assumed. (ie, Using this command is the same as using the Find command, and changing only the Direction to Up).
