How do you select an entire row and column in Excel?

Clicking on the header of the row or column will select it. So for example, to select row 3, click on the 3 at the start of it or to select column R, click on the R at the top of it. Pressing Ctrl and the spacebar will select the current column. Shift and spacebar will select the current row.
