Often while editing a chart, you may need to separate a group of symbols to make room for more. You can accomplish this by using the Symbol Select To End commands. These commands select all symbols from the coordinate of the currently selected symbol to the end of the chart, in the direction indicated by the command (Right, Left, Up, Down).
Once selected, use the Symbol Move command to move the entire group as desired. Remember that the cursor is positioned at the top left corner of the group when moving.
