on its name. When selected, the tool’s icon
replaces the mouse pointer on your
computer screen.
Arrow Tool: Highlights objects in the
sky. To select multiple objects, press the
Shift key while making selections.
Hand Tool: Changes the direction in
which you are viewing. Use this tool to
drag the sky to the left or right, up or
down, until you reach the area you want to
see.
Tip: When using any other tool, you can
temporarily switch to the Hand tool by
holding down the keyboard’s space bar.
Constellation Tool: Selects
constellations. Choose this tool and click
anywhere in the sky to select the
constellation that contains that point.
Location Scroller: Changes the latitude
and longitude from which you are
observing. Dragging up or down adjusts
your latitude, while dragging left or right
adjusts your longitude. For example, while
viewing from Earth, you can use this tool
to quickly travel anywhere on the Earth’s
surface.
Tip: This tool is particularly useful when
you’ve lifted off into space and want to
adjust your view of the planet below you.
Angular Separation Tool: Displays the
angular separation between two objects, as
seen from your current viewing position.
Select the tool, click on one object, and
drag to another.
Magnification Tool: Magnifies your
current view. Select the tool and click
anywhere in the window to zoom in that
direction. To magnify a specific area of the
sky, hold down the mouse button and drag
to encompass the area you want
magnified.
Tip: Holding down the Ctrl key (Windows)
or the Option key (Macintosh) while using
the Zoom tool zooms you back out.
QTVR Tracker Tool: Changes your
viewing direction. Unlike the hand tool,
you don’t drag the sky around. When you
hold down the mouse button, the cursor
changes from a bull's eye icon to an arrow
icon that points in the direction you move
the mouse. The sky will move in the direc-
tion you are moving the cursor, and moves
faster the further you move the cursor with
the mouse button down. If a line appears in
front of the arrow cursor, it means you
have reached the limit of scrolling in that
direction. The QTVR tool is a fast way of
moving around the sky.
Adaptive Hand Tool: By default, the
adaptive hand tool is selected. This tool
allows you to change your viewing
direction. However, unlike the regular
Hand Tool, the adaptive hand tool can
change to other tools automatically. For
example, it will change to a selection tool
when you point to a selectable object, a
location scroller when viewing from space
or an angular separation tool when you
click-hold on an object and drag to
another.
