Coords (Prefs Menu)

Movement of the mouse is displayed as positions from the origin (the lower
left corner of the screen - (0,0)).  Pressing and holding down either mouse
button will temporarily reset the origin as the current position of the
cursor.  As the mouse is then dragged, the coordinates will show the cursor
position relative to its starting position.  Using this information, you
can create accurately sized and positioned objects.

* The OriginUL option in the Prefs menu changes the origin location
  to the UPPER LEFT.

TIP:  If you are trying to accurately position an brush using the
     coordinates, and find that you cannot move the mouse precisely enough,
     use the keyboard to position the brush in increments. If you hold down
     either Amiga key to the left or right of the spacebar, you can use the
     cursor (arrow) keys to move the brush up and down or left and right.

NOTE: You can have DPaint automatically load with this option selected by
      entering 

                                  Coords

     exactly as it appears in the Prefs menu, into the Tool Types area
     of DPaint's program icon.

     Please consult your AmigaDOS manual or "The Buddy System for AmigaDOS"
     for details on changing Tool Types.
