If you wish to insert a level, record, item, value set, or value to a dictionary, first position the cursor in the location where you want to insert the dictionary element, then do one of the following: click on the toolbar; or press the Insert (Ins) key; or, from the Edit menu, select the "Insert [element]" option. You can insert from either the tree or view — in either case, the dictionary's menu bar and popup menu listing (displayed if you right-click over a tree item or the view) are context-sensitive. If you insert to the wrong place, press the Esc key to stop inserting. Use undo if you completed the insert to the wrong place.
