Mouse Shortcuts

Setting Object Properties with the Mouse

You can use your mouse (left button) in the 2D Graphics window to set several object properties that would otherwise require you to enter numerical position data.

Object	Result of Clicking Mouse in 2D Graphics Window
Facility, Place, Target	With the Basic Position page open, sets the position parameters to the location of the mouse click.
Area Target	With the Basic Centroid page open, sets the position parameters to the location of the mouse click. With the Basic Boundary page open and the Type set to Pattern, places a boundary point at the location of the mouse click. You can do this repeatedly to define the entire boundary of the Area Target.
Aircraft, Ship, GroundVehicle	With the Basic Route page open and GreatArc selected as the Propagator, places a waypoint at the location of the mouse click. You can do this repeatedly to define the entire route of the vehicle.
LaunchVehicle	With the Basic Trajectory page open and SimpleAscent selected as the Propagator, sets the launch or burnout position parameters to the location of the mouse click.
Line Target	With the Basic Path page open, places a line point at the location of the mouse click. You can do this repeatedly to define the entire line target.
Missile	With the Basic Trajectory page open and Ballistic selected as the Propagator, sets the launch or impact position parameters to the location of the mouse click.

2D Graphics Mouse Scroll Wheel Shortcut

The mouse scroll wheel can be used to zoom in and out of the 2D Graphics Window. Moving the mouse scroll wheel away from you zooms in, moving it towards you zooms out.

If you zoom in multiple times using the zoom in button and then zoom out with the mouse scroll wheel the view may inadvertently zoom in the first time the zoom out button is used. The zoom in/out buttons work off a stack of zoom levels and zooming out sets the zoom level to each previous zoom level. Since the mouse scroll wheel does not save to the zoom level stack it is possible to make the zoom area larger than the next zoom out level on the stack. Clicking the zoom out button again will allow you to continue zooming out.

3D Graphics Key and Mouse Combinations

The key and mouse combinations in the following table enable you to adjust your camera position, camera reference point, and view position and direction in the 3D Graphics window easily and quickly. When you perform the following key and mouse actions, hold down the appropriate mouse button and drag the mouse, unless otherwise indicated.

Key + Mouse	Action in 3D Window
Left	Sweeps the camera position with respect to the camera reference point. For example, if the camera reference point is the center of the Earth (the default Home View), this action rotates the globe, all objects on or around the globe, and the stellar background in any direction around the Earth's center.
Right	Zooms the camera position in and out with respect to the camera reference point.
Shift + Left	Sweeps the camera reference point with respect to the camera position. For example, if you do this in the default Home View, the Earth will move out of the center of the window.
Ctrl + Right (click)	Undoes a movement of the camera reference point that results from Shift + Left (above).
Alt + Left	Restricts rotation to the horizontal direction with respect to the camera reference point. In the default Home View, this limits the Earth to rotation about its poles.
Ctrl + Left	Restricts rotation to the vertical direction with respect to the camera reference point. In the default Home View, this limits the Earth to rotation about an axis that passes through the equator at the prime meridian.
Shift + Left (double-click)	Shifts the view perspective to the object at the location of the mouse pointer. This has the same effect as opening the View Position and Direction dialog and selecting that object as the To and From direction. This key-mouse combination works if the mouse is pointing to the object's marker or to any part of its graphical representation, e.g., a vehicle's orbit, route or trajectory, an area target's boundary, a sensor's cone, etc.
Shift + mouse scroll wheel	Rolling up the mouse scroll wheel increases the animation time and rolling down decreases the time.
Mouse scroll wheel only	Zooms in and out of the 3D Graphics window.
Middle	Twists the camera around the vector to the camera reference point.
