Viewing, Scaling And Panning The Timeline

Viewing The Timeline

Click the Timeline Tab located at the top of the flow area to switch the work area view to the timeline editor. The F7 keyboard shortcut will also open the timeline tab. Pressing the F4 key with the cursor over the timeline view maximizes the view on the screen. Press again to return it to the previous size.

Panning/Scrolling The Timeline

To pan the timeline view left or right, click on the middle mouse button and drag to the left or the right. Alternately, use the standard scrollbars at the bottom of the view.

Scaling The Timeline

To change the scale of the timeline view, use one of the following methods:

Using The Toolbars

The scale buttons are located in the top left toolbar. The Fit button attempts to re-scale the view so that all currently-visible tools fit within the timeline view. The buttons with the magnifying glass icons will scale the graph view in or out. To zoom into the selected region, use the Zoom To Rectangle button by click-dragging the rectangle.

Using The Axis Labels

Place the mouse pointer over the darker labels for the horizontal axis and click-drag to resize the timeline view. The view is scaled with the position of the mouse pointer as center.

Using The Mouse

Place the mouse pointer over the timeline view. Click and hold the middle mouse button. While the middle mouse button is held down, click once on the left mouse button to zoom in and once on the right button to zoom out.

Using The Keyboard

Several keyboard shortcuts can be used to scale the display of the graph view while the spline editor is active. The + and - keys on the numeric keypad will scale in and out of the timeline. Use Ctrl-R to enable scale to rectangle mode.
