The Instrument Escort can be accessed in one of the following two ways:
Left-click on the instrument name icon (Example:) within the chart toolbar.
Right-click in the charting area to bring up the chart context menu, then select Settings followed by the Select Instrument menu item.
The instruments window will appear, displaying the features of that particular instrument.
