+.B \-lock
+Tells the running xscreensaver process to lock the screen immediately.
+This is like \fI\-activate\fP, but forces locking as well, even if locking
+is not the default (that is, even if xscreensaver's \fIlock\fP resource is
+false, and even if the \fIlockTimeout\fP resource is non-zero.)
+
+Note that locking doesn't work unless the \fIxscreensaver\fP process is
+running as you. See
+.BR xscreensaver (1)
+for details.
+.TP 8
+.B \-version
+Prints the version of xscreensaver that is currently running on the display:
+that is, the actual version number of the running xscreensaver background
+process, rather than the version number of xscreensaver-command. (To see
+the version number of \fIxscreensaver-command\fP itself, use
+the \fI\-help\fP option.)
+.TP 8
+.B \-time
+Prints the time at which the screensaver last activated or
+deactivated (roughly, how long the user has been idle or non-idle: but
+not quite, since it only tells you when the screen became blanked or
+un-blanked.)
