  1. Cells

A Cell is the intersection of a row and a column. The highlighted rectangle on the cell is the cursor but is known as ‘cell pointer’ which enable users to move around the sheet. They can be identified by the combination of column header (e.g. ‘A’) and the row header (e.g. ‘1’) to give cell A1.

A group of highlighted cells in a worksheet is referred to as a Range.

  1. Fill Handle

This is a small black square at the corner of selected cells. The cursor changes to a black cross when moved to it.
