Zoom

The Scale popup menu on the Chart toolbar is set to the standard NOAA levels allowing direct jump to the range and zoom scale desired.

The cell detail slider will allow cells of less or more detail to be shown if they exist (only in Original MacENC Render Engine mode). For example, if you are viewing a general cell, the slider can be moved right to see any underlying harbor cell or moved left to see any coastal cell. The slider position will be reset to the center whenever the zoom scale is changed.

The New Render Engine covers this function in a different way using the Active Object Widget. See Chart View Heads Up Display (HUD) topic.
