The Insert menu is
The menu choices are grouped into the following groups:
These menu items alter the cells available in a workbook.
Cells... — The Cells... menu item opens a dialog asking the user how the sheet should be altered when new cells are inserted. The dialog lists four choices. The user can choose one of these by clicking the mouse pointer on one of the four dots. Only one choice is possible and the currently selected choice has a black dot in front.
The Shift cells right will insert a region of new cells of the size of the current selection. Cells which are on the same row as the selection and within or to the right of the selection will shift over to the right to accommodate the new cells. The Shift cells down choice will also insert a region of new cells the same size as the current selection. With this choice, cells which are in the selection or below the selection will move down to accommodate the new cells. The two other choices will act as if the user had chosen to insert rows or columns. These actions are explained above.
Columns — The Columns menu item will insert columns to the left of the current selection. The number of columns inserted will equal the number of columns spanned by the current selection.
Rows — The Rows menu item will insert rows above the current selection. The number of rows inserted will be equal to the number of rows spanned by the current selection.
Sheet — The Sheet menu item allows the user to inset a worksheet immediately following the current sheet.
The menu items insert sheet objects into the worksheet or insert content into the current cell.
