The Track List displays all of the curve tracks currently loaded into the current tab. Tracks are normally loaded external to the Curve Editor by pressing a button associated with a Track in Matinee or a Module in Cascade.
Each track in the Track list displays the name of the property associated with the track along with visibility toggle buttons for each individual curve in the track and an overall visibility toggle button. The individual curve visibility toggle buttons are color-coded to correspond to the components of a vector, with red being X, green being Y, and blue being Z. Red is also the color used for a single scalar float value. In the case of a VectorUniformDistribution, there are two sets of curves with each color having a lighter and darker version.
Right-clicking on a track in the Track List brings up the track list context menu.
