When in the Quick Leader command (and this only works for quick leader), you can Right-Click before selecting the first point to bring up a settings window. This controls your default leader settings. Things you can change:
- End style (Arrowhead)
- Straight or spline leader lines
- Number of points (or bends) in the leader line
- Angle constraints for your lines
- Text justification for both Left and Right side text
- What the annotation is (block, text, etc). The annotation is then associated with the leader (how it normally handles text).
