Keyframes (or keys) store character poses and positions. Changes made to a pose in a regular frame will not be saved, so you need to create a keyframe every time you want to adjust a character.

Keyframes are found on the Timeline.

By default, they are repesented as blue-colored rectangles.
This color can change when a keyframe is only present on some of the Animation Tracks in the folder. In such a case, this keyframe will be colored rose when the folder is closed:

See Animation Tracks to learn more about tracks and folders.
