-   The standard X cursor names from :file:`cursorfont.h` can be used, without the

+   The name of the mouse cursor to display while the pointer is over the widget.
+   Tk provides a portable set of cursor names available on all platforms
+   (for example ``"arrow"``, ``"watch"``, ``"cross"``, or ``"hand2"``);
+   the standard X cursor names from :file:`cursorfont.h` may also be used,
+   without the ``XC_`` prefix (so ``XC_hand2`` becomes ``"hand2"``).
+   The full list of names, including the platform-specific ones,
+   is given in the :manpage:`cursors(3tk)` manual page.
+   You can also specify a bitmap and mask file of your own.
    On Windows a cursor file (:file:`.cur` or :file:`.ani`) may be used directly,
    giving its path preceded with an ``@``, as in ``"@C:/cursors/bart.ani"``.
