There are two methods that can be used to add a line or arrow to a log:
1. By clicking on the Line button on the Toolbar. Next using the left mouse button click on the location of the starting point of the line or arrow. Then while holding down the left mouse button, drag the cursor to the end of the line or arrow and release the mouse button. The Edit Lines form will then be displayed.
2. By selecting the Lines menu item from the Edit menu or popup menu and then clicking on the Add button on the Edit Lines form. Using this method, the location of the line must be specified on the form.
