The Edit Menu
This menu is massively useful, largely because it operates between documents. But you can use it to work and build up a desired object within a single document. There are two clip boards.
The public paste board which is common to all applications. It permits you to clip and paste images from the screen to other documents and programs and vise versa. The operations of the screen are "Copy" and "Paste". You can choose to enclose the clipped image of the screen in a dark border if you wish by setting the appropriate check box in the preferences window. The "Copy Histogram" menu item will place the histogram on the public clip board. You can also past text into the "Filter" function with this clip board. This clip board is the one that the 3-D image as well as text data is put into. You can clip and paste icons in the script window using this board as well, but the icons can not be pasted into any other program (they include a bunch of code than only this program understands).
The private paste board is for the "Big Array" which permits you to clip and paste the whole enchilada. It is accessed through the "Copy Big" and "Paste Special" menu items. When you go to paste you may choose to instead add or multiply the "Big Array" on the clip to the "Big Array" in the front document. So for example if you wish to enter two binary files into the real and imaginary parts you should first enter one into the real part then multiply it by "i" and then saving this to the big clip. Then after you have entered the next binary into the real part you can then "Add Big Array" to that entry. The result is the first file in the imaginary part and the second in the real part.
