Basic map controls are a row of control buttons located underneath the menu bar. This tutorial will go over these buttons as well as keyboard and mouse shortcuts.

Each button stands for the following:

• Full Extent: Returns the zoom level to the full extent of the data being viewed.
• Move Left (West): Moves the current view left or geographical west.
• Move Up (North): Moves the current view up or geographical north.
• Move Down (South): Moves the current view down or geographical south.
• Move Right (East): Moves the current view right or geographical east.
• Zoom In: Zooms the current view 1x based on the mouse click point.
• Hand: Moves the current view in both the x and y direction based on a left click and hold of the mouse.
• Zoom Out: Zooms the current view out 1x based on the mouse click point.
• Marker: Allows you to add a marker to the current view. Learn more about markers.
• Identify: Engages the identification mouse tool. Clicking on the map will show the identification dialog and append the value of the active and snapshot layers at the click point. Learn more about identification.
• Search: Shows the location and variable search tool. Learn more about the search tool.

There are several keyboard shortcuts in conjunction to the map control buttons. They are:

• Left Arrow Key: Moves the current view left.
• Right Arrow Key: Moves the current view right.
• Up Arrow Key: Moves the current view up.
• Down Arrow Key: Moves the current view down.
• Page Up Key: Zooms the current view in 1x based on the current view's center point
• Page Down Key: Zooms the current view out 1x based on the current view's center point.
• Home Key: Returns the zoom level to the full extent of the data being viewed.
• Control Left Key: Rotates the current view counter-clockwise. (Note after you pass 90 degrees from the horizontal, background overlays become unavailable, WMS maps still work)
• Control Right Key: Rotates the current view clockwise. (Note after you pass 90 degrees from the horizontal, background overlays become unavailable, WMS maps still work)

A keyboard shortcut menu is also available when you right click your mouse in the viewer menu, the menu functions work when you left click on them. The menu also includes a new tool called the Magnifier.

The Magnifier places a "magnifying glass" in the viewer that magnifies the area inside the circle.

Right clicking in the magnifier will bring up a menu selection to close to magnifier.
