+.B \-throttle
+Temporarily switch to ``blank screen'' mode, and don't run any display modes
+at all, until the screensaver is next de-activated. This is useful if you're
+using a machine remotely, and you find that some display modes are using too
+much CPU.
+
+(If you want to do this \fIpermanently\fP, that is, you want the screen saver
+to only blank the screen and not run demos at all, then set the \fIprograms\fP
+resource to an empty list: See
+.BR xscreensaver (1)
+for details.)
