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
