You can right-click on the graph at any time for a menu to format the graph.
      Once you click on the graph, the following key combinations can be used to control most of these options as well:
  Ctrl-B - makes graph thicker
Ctrl-N - makes graph thinner 
Ctrl-P - switch background between gray and white (for copying to Word)
Ctrl-F - display function type options (You can also right-click on the y =.)
Ctrl-E - switch between normal axes and extended axes with arrows on pos. ends
Alt-E - switch between normal axes and extended axes with arrows on all ends
Ctrl-R - switch between no arrows, arrows on pos.  axis ends, and arrows on all
          axis ends  (Alt-R changes the position of these arrows one pixel at a time.)
Alt-H - hides/shows the trace point on the graph.
Alt-A - hides/shows the arrows on the ends of the graph itself.
Ctrl-U - switch between graph filling space and a uniform grid
Ctrl-L - changes how large the arrows are on the graph, increases and then
       starts over with a small size.  Keep hitting this key to find the size you want.
Ctrl-Y - hides/shows vertical asymptotes (if present).
Alt-N - hides/shows the numbers on the axes.
Shift-Alt-T - hides/shows the tick marks on the axes.
In Area Function Mode:

With Digital Signature:

Ctrl-T - shows/hides tangent line to area function
Ctrl-A - shows/hides whole area function
Ctrl-D - shows/hides F'(x).

Ctrl-C - copies the graph to the clipboard as an EMF (a vector graphics image)
               (This prints great, but doesn't look as great on the screen.)

Alt-C - copies the graph to the clipboard as a BMP (This prints well, though not
               as nice as the EMF, but it will look nicer on the screen. )
