Zoom > Double Zoom (Manage Menu)

This command doubles the size of the view in the active window, i.e. it doubles the zoom factor.

These alterations to the visible section and the zoom factor can be undone with the Zoom > Previous View command.

If this command is carried out using the NUM + key on the numeric keypad, it will apply to the window over which the mouse pointer or crosshairs are located, which may not be the active drawing window. In this case, the area around the current crosshairs position is changed.
