the time is shown in the legend, left-clicking on it will bring up the
Time dialog and right-clicking on it will set the time to the present.
Clicking on the RA will bring up the "Enter new RA/dec" box; clicking
on the galactic coordinates will bring up a box to enter galactic
coordinates for the chart center;  and so on.  (Tooltips are provided
for all of these,  but in a somewhat unusual place:  on the application
title bar.)
                                                            
   When you turn the "Second Time" option on,  Guide will ask you to
select a time zone.  The legend will then contain the "usual" time,
but will also show you the "second time" in a different zone.  This
can be used to ensure that,  for example,  the legend shows the time
in UT,  but that you can still have the local time shown for reference,
or perhaps the local sidereal time,  or some other time zone.  (Sidereal
time isn't normally thought of as a "time zone",  but treating it in
this manner can be useful.)
                                                            
   The "caption" refers to text you may wish to add to the legend area,
such as "Occultation of P17 by Pluto" or "Area around M-49".  You may
wish to add multiple lines;  suppose, for example,  that you want to
make a chart showing the asteroid 111 Ate passing through the galaxy
M-104,  and the chart is for use by the East Overshoe Astronomical
Society. You might want the following three-line caption:

Asteroid 111 Ate
(As seen in area of M-104)
East Overshoe Astronomical Society

   To enter these three lines,  you would first clear any existing
caption using "Clear Caption".  Next,  you would click on "Add to
Caption" and enter "Asteroid 111 Ate".  You would then click the
option twice more and enter the remaining two lines. Make sure that
the caption is turned on (by clicking on "Caption Off",  if
necessary).  When you leave the menu, the chart will redraw and the
new caption will be shown.

   You also can change the "Layout" of the legend.  A "Vertical"
layout makes the legend much taller than it is wide;  a "Horizontal"
is wide. You can switch the legend between the bottom or top of the
chart,  and move it to the left, right,  or center. By default,
Guide uses a vertical layout in the bottom left.

7f:  Measurement Markings (Ticks,  Grids,  etc.)      

   The Measurement Markings menu controls the features to measure
positions and sizes in Guide.  The menu looks something like this:

Ticks
Grids
Side Labels
Hatches
