The list of valid settings for gdk_screen_get_setting()?????

[Eduard Bagrov <ebagrov gmail com>]

Hello!
The latest version of documentation of gdk says that the function
gdk_screen_get_setting()
"Retrieves a desktop-wide setting such as double-click time for the
GdkScreen screen.
FIXME needs a list of valid settings here, or a link to more information. "

Where can I find the list of the settings?
