Argo Zoom Menu

This page describes each menu item in the Argo Zoom menu. Except for the explicitly labeled vertical zoom options, all zooming in Argo is horizontal zooming.

You can zoom using the Zoom menu or the mouse. To use the mouse, hold the shift key and click: left click zooms in, right click zooms out. To zoom in on an area, drag the mouse over the area while pressing the shift key and the left mouse button (middle mouse button for a 3-button mouse).

When you zoom, the height of the feature glyphs remains the same. To change feature glyph height and other display settings, use the Feature Map Options window.
