6. COPY, CUT, PASTE
These operations allow you to copy or move information between different applications or within the same application. They use the clipboard (much like that on a computer) to temporarily store the information. Cutting will delete the information; copying will leave the information so that it can be pasted in another location.

You can use the PASTE operation as many times as you like. The expression on the clipboard will remain the same until you copy and paste or cut and paste another expression. The expression can be pasted into the graph menu.
You can use the CUT operation the same way as COPY. Using CUT is not the same as deleting an expression. When you delete an expression you cannot retrieve it.
