[Changing the bearing with index line 1] 
When index line 1 is clicked on, the shape of the cursor changes to  . 
All the index lines rotate centring on the index line reference position (starting point). 
 
[Changing the bearing at a clickable trisectional end segment position of index lines 2 to 8]     
When one of the index lines 2 to 8 is divided into three equal segments and the mouse button is clicked 
on both ends of the line segments, the cursor shape changes to  . 
Index lines 2 to 8 move, forming a circle centring  on the reference position while the index line 
reference position (starting point) is fixed. 
 
[Changing the interval at a clickable trisectional centre segment position of index lines 2 to 8]   
When one of the index lines 2 to 8 is divided into three equal segments and the mouse button is clicked 
on the middle line segments, the cursor shape changes to  . 
Index lines 2 to 8 move in parallel to index line 1. 
 
If a clickable segment is 2 cm or less, the change of interval mode is always activated.
