The Search » Advanced branch of Settings has the following options.
This setting causes the editor to use the active file path for setting the Find / Replace in Files default directory. By default the editor uses the previous path used in the dialog for this.
If this option is selected, and "Highlight all items found" is selected in the Find dialog, any strings matching the search string will remain highlighted after a search is executed. Users may toggle the selection off using the Highlight All Selected option in the toolbar or the View tab.
If this option is selected, and the option Continue find at end of file is selected under Settings » Search » Miscellaneous, a brief animation will be shown when the search passes the top or bottom of the file to indicate that the search is being continued from the other end of the file.
