Count Count
The Count tool allows the user to calculate the cells. It can be used in two ways.
First the cell in which the result is to be is selected, then the Count tool is chosen and after that the cells which the user wants to count are selected. The result appears in the cell selected at the beginning.
Alternatively, the cells which the user wants to count are selected first, and then the Count tool is chosen. If there is only one line the result is inserted after the line selected. If multiple lines had been selected, the count of cells in each column is inserted under each of the columns. The count of cells in each line can be calculated by holding Shift when the Count tool is chosen. The result then appears after each of the lines.
