You may also want to add notes right on the Gantt chart. You can do this by adding a text box. First, click the Insert menu and click Drawing. You will see this toolbar:

Next, click the Text Box button (). Then, your cursor will turn into a crosshair so that you can draw the text box in your chart.

Once you release your cursor, you will be able to type in the text box.

You can move the text box simply by dragging it, or resize it by dragging its outer edges. Or, to delete the text box, click it to select it and then press the Delete key on your keyboard.
