How to quickly and easily create labels (text with arrows)?
To create labels quickly, use the Line Type Label tool found in the Tools > Annotations menu.
In the Status Bar at the bottom you can choose the text size, set the properties by clicking the browser button (...), type the desired text in the Text field, or let the program determine the text based on the line type of a line.
Click on a line with nothing typed in the Text field to get a label for that line type.
Or click anywhere on the design to place the point of the arrow, enter the annotation text in the Text field, then click again to place the text portion of your label. Whatever is typed in the Text field will be displayed with the arrow.
By placing the arrow point away from a line, you'll be able to quickly make annotations without the need to create a separate arrow and text object.
