You can use the mouse to manipulate items and manage the way data is displayed in the Vicon Nexus window. Standard mouse actions can also be combined with keyboard keys.
To help you use Vicon Nexus efficiently, this section provides lists of shortcuts:
Common hot keys and shortcuts
The following mouse actions and hot keys are available throughout Nexus, where applicable/available:
| Task | Keys and mouse |
|---|---|
| Start/stop capture | CTRL+Enter |
| Select individual items | Click |
| Select items within a bounding outline | ALT+click and drag |
| Select multiple non-consecutive items | CTRL+click |
| Rotate/orbit | Click and drag |
| Zoom | Right-click and drag |
| Translate/Move | Click wheel button (or left-and-right-click) and drag |
| Scroll forward or backward through a list | Rotate mouse wheel |
| Undo | CTRL+Z |
| Redo | CTRL+Y |
| Save currently enabled subject data to the current trial's .c3d file (equivalent of clicking Save on the File menu) | CTRL+S |
| Reset Core Processor | CTRL+R |
| Esc | Exit current mode (labeling, etc) |
| Unset all cameras' Bumped status | CTRL+SHIFT+B |
The behavior of the ALT GR key depends upon the regional settings specified for your keyboard in the Windows operating system. In some regions, the behavior of this key is identical to that of the ALT key, while in other regions the ALT GR key functions as if the ALT+CTRL keys were pressed together. Nexus assumes the latter behavior.
If you want to use the ALT GR key as if it was the ALT key, you must change the regional settings for your keyboard to use the US layout, which assumes identical behavior for these two keys. You change your keyboard language settings in the Text Services and Input Languages dialog box, accessed from the Languages tab in the Regional and Language Options dialog box in Windows Control Panel. For more information, see the Microsoft Windows help.

Shortcuts for visualizing graph data
The way the graph that is displayed in a Graph view depends on whether the system connection is live or offline and whether an individual point or a range has been selected for plotting.
When zooming into or out of graph data, the display of grid lines in the view pane can be set to guide the eye toward the selected area of focus. Major grid lines remain at their normal weight, while any minor grid lines gradually fade. To obtain this behavior, open the Options dialog box (F7) and under General View Options, select Graph. In the Properties pane on the right, ensure Show Minor Grid Lines is selected.
Zoom an axis (x or y)
All component graphs in a single workspace maintain the same scale for both the x- and y-axes. The x-axis is shared across all components, but each component has its own y-axis. The y-axes may show different ranges, but represent the same number of values.
- Offline: The portion of the specific component trace displayed in the view pane is centered around the point where the mouse was clicked. All other component views are scaled by the same amount, with the vertical range centered on the median value of the visible portion of all the selected traces.
- Live: The x-axis, the workspace is centered around zero, keeping zero on the right edge of the workspace and changing the values displayed on the left.
Zoom selected range of frames
- Offline: The y-axis displays only the selected area of the specific trace and the x-axis displays only the selected frames.
- Live: This type of zooming in the x-axis is disabled to ensure that the live frame is always on the right of the graph.
Pan across an axis (x or y)
- Offline: Each component in the y-axis can be panned independently.
- Live: Panning in the x-axis is disabled to ensure that the live frame is always on the right of the graph.
Open a Quick Reports window
In addition to displaying a Graph view, you can also open a Quick Reports window (press F4), which enables you to display multiple graphs of model outputs normalized over the gait cycle. For more information, see Quick Reports in the Vicon Nexus Reference Guide.
