Double-click cell A8

Excel is ready to edit cell A8.

Press Home Key

Excel moves the cursor to the beginning of the word "Electricity".

Press the spacebar twice
Press Enter

Excel moves "Electricity" over two spaces, and makes cell A9 the active cell.

Excel truncates "Electricity" and does not allow it to spill over into the next cell. Why? The next cell, B9, is not blank, but contains data. Although truncated, the entire cell contents is still contained in the cell.

Now you try.
