-Whether the screen saver should lock the screen when it activates.

-.B Lock After
-If \fIRequire Password\fP is selected, this controls the length of
-the ``grace period'' between when the screensaver activates, and when the
-screen becomes locked. For example, if this is 0:05:00,
-and \fIBlank After\fP is 0:10:00, then after 10 minutes, the screen
-would blank. If there was user activity at 12 minutes, no password
-would be required to un-blank the screen. But, if there was user activity
-at 15 minutes or later (that is, \fILock After\fP minutes after
-activation) then a password would be required. The default is 0, meaning
-that if locking is enabled, then a password will be required as soon as the
-screen blanks.

+The running saver will be restarted every this-many minutes even in
+\fIOnly One Screen Saver\fP mode, since some savers tend to converge
+on a steady state.

+.B Lock Screen After
+This controls the length of the ``grace period'' between when the
+screensaver activates, and when the screen becomes locked. For
+example, if this is 5 minutes, and \fIBlank After\fP is 10 minutes,
+then after 10 minutes, the screen would blank. If there was user
+activity at 12 minutes, no password would be required to un-blank the
+screen. But, if there was user activity at 15 minutes or later (that
+is, \fILock Screen After\fP minutes after activation) then a password
+would be required. The default is 0, meaning that if locking is
+enabled, then a password will be required as soon as the screen blanks.

+.B Preview
+This button, below the small preview window, runs the demo in full-screen
+mode so that you can try it out. This is the same thing that happens when
+you double-click an element in the list. Click the mouse to dismiss the
+full-screen preview.

+.B Settings
+This button will pop up a dialog where you can configure settings specific
+to the display mode selected in the list.
+.SH SETTINGS DIALOG
+When you click on the \fISettings\fP button on the \fIDisplay Modes\fP
+tab, a configuration dialog will pop up that lets you customize settings
+of the selected display mode. Each display mode has its own custom
+configuration controls on the left side.
+
+On the right side is a paragraph or two describing the display mode.
+Below that is a \fBDocumentation\fP button that will display the display
+mode's manual page, if it has one, in a new window (since each of the
+display modes is actually a separate program, they each have their
+own manual.)
+
+The \fBAdvanced\fP button reconfigures the dialog box so that you can
+edit the display mode's command line directly, instead of using the
+graphical controls.
+.SH ADVANCED TAB
+This tab lets you change various settings used by the xscreensaver daemon
+itself, as well as some global options shared by all of the display modes.
+
+.B Image Manipulation
+
+Some of the graphics hacks manipulate images. These settings control
+where those source images come from.
+(All of these options work by invoking the
+.BR xscreensaver\-getimage (1)
+program, which is what actually does the work.)
