index lines in the trackball operation unit (Individual mode)
[Changing the bearing at a clickable trisectional segment position on both sides]
1 Place the cursor on the lines on both sides of the lines that were created by dividing
one of the index lines 1 to 8, which can be clicked, into 3 equal sections and click the
button.
The shape of the cursor changes to
and when the mouse button is clicked, the bearing of
the parallel index lines can be changed.
2 Move the cursor to the bearing to be set.
The bearing of the parallel index lines changes together with the cursor.
3 Click the mouse button.
The parallel index lines are fixed.
[Changing the distance at a clickable trisectional middle position]
1 Place the cursor on the middle line of the lines that were created by dividing one of the
index lines 1 to 8, which can be clicked, into 3 equal sections and click the button.
The shape of the cursor changes to
and when the mouse button is clicked, the interval of the
parallel index lines can be changed.
2 Move the cursor to the interval to be set.
