Resize the Arrow

There are two ways to resize the arrow. You can increase or decrease the length and increase or decrease the width.

  1. Click Select and select the arrow.

    If the arrow is close to a lane or a band, the easiest way to select the arrow is to use the cursor to drag a small box through the center of the arrow.

  2. When the arrow is selected, it will be displayed with a dotted line, and the cursor changes to four arrows.

  3. To lengthen (or shorten) the arrow, move the cursor to the end. A small arrow is displayed. Drag it to the right to lengthen the arrow, or drag (push) it to the left to shorten it.

  4. To increase (or decrease) the arrow head's width, select the arrow and move the cursor to the bottom (or top) of the selection. A small vertical arrow is displayed. Drag it up or down to change the width.

  5. Click anywhere else on the image to de-select the arrow when you have finished.
