Make Your Selection
By default, if you select the text in a column of cells, you’ll also select the text in the intervening rows as well. To select just the text in a particular column, first select some or all of the text in a single cell and then hold down the Command key. Now, drag the cursor across some the text in the cell below the first cell and continue doing this for all the other cells in the column. This time, TextEdit ignores the intervening rows unless you explicitly select them as well by Command-dragging across the text.
This Command key trick works nicely in regular word processor documents, too, enabling you to copy the text in the first, third, and fourth paragraphs (for example) while skipping the second paragraph. Holding down the Option as well as the Command key while selecting or deselecting adds another level of subtlety, non-contiguous text selection, with a crosshair cursor now appearing that allows chunks of text down to individual letters to be added or removed from the selection.
Figure 6 Holding down the Command key while selecting text lets you add and remove portions of text from your initial selection.
