5 Drag the Playhead to 0:04 in the Timeline.
6 Now, go to the application menu and select Timeline | Toggle Pin. This will unsync the Pin from the Playhead.
Again, the Pin is the small control directly beneath the Playhead when unsynced.
7 Grab the Pin and drag it to 0:00 in the Timeline. This will pin the elements current properties to the 0:00 point
without the need to manually insert keyframes. Keep the Playhead itself at 0:04.
8 Now, select the element with the Selection tool and in the Properties panel, modify the following properties:
• Location X: 480 px
• Background Color: #900000
• Rotation: 480 deg
Notice that we now have transition bars appear on the Timeline without the need to set any keyframes whatsoever.
9 Go to the application menu and select Timeline | Toggle Pin to sync the Pin. We can also toggle the Pin through a
keyboard shortcut as expressed earlier in this chapter.
10 We can now either scrub through the Timeline by dragging the Playhead back and forth, or hit the Play button to
view the full sequence. When played back, the element should appear to roll along the Stage from left to right,
changing from gray to red as it does so.
Note: Note that, while in this case the Pin was placed at an earlier time in relation to the Playhead within our Timeline—
that
need not be the case. We can also place the Pin at a later time than the Playhead and the same behavior will be
exhibited: current properties are pinned to the Pin position while adjusted properties align to the position of the
Playhead.
Editing transitions
Once a transition has been established, it can be adjusted through mouse interaction via the Timeline. In order to adjust
the transition delay, duration, and end we simply click-and-drag the visual transition indicators within the Timeline
itself.
