Selecting Symbols
Symbols in the chart may only be operated on when they are selected. When a symbol is selected, it is surrounded by eight selection handles, or a dotted rectangle if multiple symbols are selected.
Some commands require that only one symbol be selected, while others require or allow more. Menu commands are enabled when the number of selected symbols is correct for their respective actions.
To select one or more symbols:
1. Place the cursor inside the symbol and click the mouse (or press Enter).

When one or more symbols is selected, the selection of any other symbols in the chart will be dropped. If you hold the Shift key down while selecting, the previous selections will be retained.
