Placing Scenes and Actions on the Timeline

An existing scene can be placed on the timeline by dragging and droppping a thumbnail from the Scenes tool. A new scene corresponding to the current ChimeraX contents can be created and added to the timeline by clicking the plus-sign icon (white on a blue circle). The scenes can be dragged horizontally to different positions on the timeline.

Adjust Time: Clicking the negative and positive numbers allows adjusting the length of the timeline by subtracting and adding seconds.

Actions: the three icons on gray circles represent (from left to right) represent rocking, rolling, and precession. Each type of action can be placed on the timeline any number of times by clicking and dragging the respective icon, and its start and stop times adjusted by dragging the left and right ends of the action bar horizontally on the timeline.

A scene or action can be removed from the timeline by clicking its representation on the timeline and pressing the delete key.

Playback and Scrubber

The scrubber is the red vertical line indicating position on the timeline. Clicking the timeline places the scrubber, and dragging the the scrubber horizontally shows the corresponding segment of the animation as per the speed and direction of dragging. Clicking the play button plays the animation from the current scrubber position to the end, at the speed indicated by the timeline length in seconds. During playback, a pause button ⏸ is shown and can be clicked to halt playback in progress. Clicking the rewind button ⏮ places the scrubber at the beginning of the timeline.
