How to Select Cells in Excel 2013
Move the cell cursor to the first cell of the first range you want to select. Press F8 to turn on Extend Selection mode.
You can also select a cell range with the keyboard without turning on Extend Selection mode. Here, you use a variation of the Shift+click method by moving the cell pointer to the active cell in the range, holding down the Shift key, and then using the direction keys to extend the range. After you’ve highlighted all the cells that you want to include, release the Shift key.
