Keyframe Indicators

A number of colours are used in numeric fields to indicate that keyframes are present in the channels associated with the fields.

Indicator | Example
--- | ---
A blue bar under a numeric field indicates that one or more keyframes are present on this channel. |
A yellow bar under a numeric field indicates that a keyframe is present on this channel at this point in time. |
A dotted yellow bar under a numeric field indicates that this channel is linked to another channel using an expression. In this case, the numeric value is also greyed out, as the value can not be modified. The name of the linking channel is also displayed as part of the tooltip. |
A yellow character in a numeric field indicates that a numeric value is changed, but a keyframe is not set. Once a keyframe is set, the character colour returns to grey, and the keyframe indicator under the value is set. |

When working with keyframes and displaying selected channels, there are also hotkeys available and a contextual menu with options based on the state of the selected field. See Selecting Channels Automatically.
