To set the Julia seed location
1) With a Julia window active, on the Location menu, click Set Julia Seed.
2) Specify the horizontal coordinate of the Julia seed in the Julia X text box, then press the TAB key.
3) Specify the vertical coordinate of the Julia seed in the Julia Y text box, then press the TAB key.
To interactively explore different Julia seed locations
Hold down the alt key as you click or drag in a non-Julia window. This is known as dragging the Julia seed, or Julia seed dragging.
If you have multiple Julia windows open, the last active Julia window will be updated.
