You will now find yourself back in the graphics
screen with a rectangle representing the size of the
GROB to be pasted.
Move the rectangle to the desired position and press
The contents of the stored GROB will appear.
Simple Animations
This pasting technique can be very useful in building a Sketch, particularly when used in conjunction with the
ability to capture
PLOT
animations by pasting the same image in successively moved locations on each of the pages. Holding down
the key will move rapidly through the sketches and animate them but the speed of the animation
may be too fast to work properly. If you can program then you can automate the animation quite simply. An
example of a simple programmed animation can be found on the author's website
(http://www.hphomeview.com). It consists of a pair of seals tossing a ball back and forth.
Capturing the PLOT screen
To capture a screen, just arrange the

the pasted GROB now had to be located on the sketch page, the
captured screen in this case is a full size image and so will be pasted in
as a fresh page rather than replacing part of an existing one.
Having pasted it into the Sketch page, you can now modify it by adding
text and other information.
One has to question, however, whether the time needed to do this and the crudity of the result make the whole
process worthwhile. If you're intending to do this to produce a set of 'cheat notes' for your next test or exam,
you would do better to spend the time studying!
