The Edit Channel Properties window allows you to edit channel properties in a small spreadsheet. To access the window, 
click on a channel in the channel list or parameter in the parameter editor, and select Channels ▸ Channel Properties.
If you select multiple channels or click on a vector parameter label, the Edit Channel Properties window will display multiple rows of data.
Channel
Label with the full parameter name.
Alias
Aliases can be assigned to channels by typing the new alias. To delete an alias, enter the channel’s original name or clear the alias.
Before / After
Allows you to choose the extrapolation method to use when evaluating the channel outside the keyframe range. Hold ⌃ Ctrl or ⇧ Shift while dragging to create a rectangle selection for setting multiple cells at the same time.
Default
Use the channel default value.
Hold
Hold the last evaluated value.
Cycle
Cycle the animation in the keyframe range. It is important for the first and last keyframes to have the same values and slopes in order to prevent jumps in the cycle.
Extend
Keep evaluating the last segment even if the time is outside the channel keyframe range.
Slope
Keep a linear slope from the last value.
CycleOffset
Cycle the animation in the keyframe range but accumulate the offset between the first and last keyframes. This is useful when creating a cycle on a translation that keeps moving forward.
Oscillate
Cycle the animation in the keyframe range but flip the value at each interval.
Auto Scope
When set to On, the channel is automatically added to the channel list when its associated node is selected.
Auto Select
When set to On, the channel is automatically selected when it is added to the channel list.
Color
Shows a button colored with the channel color. To change the channel color, click the button to open the Color Editor window.
Note
The unnamed checkbox to the right of the color button shows the state of the custom color. If the color is different from its default value, the checkbox is checked. Unchecking it resets the color to its default value.
