The Arrow option allows you to add an arrow between any two points on a view. To add an Arrow:
Select Arrow from the toolbar or the Add Tool sub-menu of the Tools menu.
Enter the first point graphically with the mouse, or enter x,y coordinates in the prompt line. NOTE: the Snap options are available in the right-click menu, if you want to snap exactly to certain coordinates.
As you move the mouse, an arrow head will appear at the point entered in step 2, and a line will connect the point to the current cursor location.
Enter the second point graphically with the mouse, or enter x,y coordinates in the prompt line, and the Arrow will be added to the view.
After an Arrow has been added, it can be moved, re-sized, formatted, etc. See the Edit Tools Overview topic for details.
