When you design your SQL statement in one of the two SQL dialogs, you can either use the Edit menu or the five 
~
~ toolbar buttons. The Edit
menu is used to copy text into the clipboard or to paste text from the clipboard in your SQL statement. The menu consists of the Undo, Cut, Copy, Paste, and
Delete menu items.
There is also the possibility, when viewing results or defining a query in the Query description window, to see and edit the individual fields in a separate window. For this purpose, you can move the mouse pointer to the desired field and press the right mouse key, then select Zoom.
The items are only available when they are usable. This means, e.g., pasting from the clipboard is only provided when something is in the clipboard. This menu item is not offered beforehand.
The Undo menu item can be used to cancel the last editing step in your SQL statement. Cut can be used to remove a previously marked section from the input screen and to copy it into the clipboard. Copy can be used to copy the marked section into the clipboard. Paste can be used to insert the content of the clipboard in your SQL statement. The object is pasted at the position where the insertion point is placed. A marked section is replaced by pasting. The Delete menu item removes the marked section without copying it into the clipboard.
You can use the following toolbar buttons instead of the individual menu items:
