Timeline Editor

The Timeline editor, identified by a clock icon, is not much of an editor, but more used to view information and control animation playback.

The Timeline.

The Timeline is one of an animator's most useful tools as it can give a broad overview of a scene's animation. The Timeline can communicate the current time frame, either in frames or in seconds, where the keyframes are of the active object, the start and end frames of your animation, markers, etc.

The Timeline has Player Controls, to play, pause the animation, and to skip though parts of the scene.

It also has some tools for Keyframes, Keying Sets, and Markers.

Main View

The main Timeline region displays the animation frames over time.

Playback/Rendering Range

By default, the Playback/Rendering Range (Frame Start 1 to Frame End 200) is a lighter shade of gray. The start and end frame can be set to the Time Cursor by pressing S or E. The Playback Range can also be set by pressing P then drawing a box.

Keyframes

For the active and selected objects, keyframes are displayed as a yellow line. For Armatures, the object keyframes and the pose bones keyframes are drawn.

Only Selected Channels can be enabled. Timeline ‣ View ‣ Only Selected Channels. For Armatures, this will draw the object keyframes, and the keyframes for the active and selected pose bones.

Markers

Markers are the small triangles, with their name near them. Markers are usually used to identify key parts of the animation.
