     * `☐ Fill Find Field with Selected Text`: When checkmarked, invoking the Find Dialog will fill the **Find What** field with the currently-selected text; when not checkmarked, invoking the Find Dialog will not change the contents of the **Find What** field (reworded in v8.4.5; previously was `Don't fill find field...`)
         * `☐ Select Word Under [caret](#caret-and-cursor "typing/insertion cursor") when Nothing Selected`: When checkmarked, invoking the Find Dialog with no active selection will fill the **Find What** field with the text under the [caret](#caret-and-cursor "typing/insertion cursor"); when not checkmarked, invoking the Find Dialog with no active selection will not change the contents of the **Find What** field; if the option above is not checkmarked, this option will be un-checkmarked and cannot be toggled.  (new to v8.4.5)
     * _Note_: The fill will only occur if the size of the active selection is 1024 characters or less. This is a fixed value and is unrelated to the `Minimum Size for Auto-Checking 'In selection'` value.
-    - In v8.7.5 and newer, if this is checked, Notepad++ will initialize the Directory to the current document's directory when you first launch [**Find in Files**](../searching/#find-in-files-tab) dialog. (Note that "first launch" means that if you change the active tab while the dialog is still open, the Directory field will not change.)  If you manually change the directory (either through typing, or using the `...` button), it will search the newly-entered directory, rather than using the directory it defaulted to.  The next time you launch the dialog, it will update the default directory again (assuming the option is still checked).  And there is a **<<** button in the dialog which will re-populate the Directory field based on the active dialog, no matter the state of this option, and whether or not the active document has changed since the dialog was launched.  (This preference replaces the **☐ Follow current doc** checkbox, which used to be present in the dialog in v8.7.4 and earlier.)

 * `☐ Use Monospaced font in Find dialog (Need to restart Notepad++)`: Changes the font from standard proportional font to a monospaced font in the text boxes in the **Find** dialog; requires restarting Notepad++ to change.
 * `☐ Find dialog remains open after search that outputs to results window`: Successful file-level searches cause the **Find** window to close; selecting this option keeps the window open always.
