This window allows you to edit channel properties in a small spreadsheet.
To access this window, click 
on a parameter and select Channels and Keyframes > Edit Channel Properties. You can get multiple rows in the table if you click on a vector parameter label.
You can also access it from the Scoped Parameters list if you click on the value column. You can get multiple rows in the table if you have many scoped parameters selected.
Channel Column
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 Extrapolation
Allows you to choose the extrapolation method to use when evaluating the channel outside the keyframe range. Holding ⌃ Ctrl or ⇧ Shift while dragging will create a rectangle selection to edit multiple cells at the same time.
Default
Use the channel default value.
Hold
Hold the last evaluated value.
Extend
Keep on evaluating the last segment even if the time is outside the channel keyframe range.
Cycle
Cycle the animation in the keyframe range. It’s important for the first and last keyframes to have the same values and slopes to prevent jumps in the cycle.
Slope
Keep a linear slope from the last value.
Cycle Offset
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 on moving forward.
Oscillate
Cycle the animation in the keyframe range but flip the value at each interval.
Color
Shows a button colored with the channel color. Click the button to open the Color Editor and change the color.
Note
The unnamed checkbox column to the right of the button shows the state of the custom color. If the color is different from its default value, the checkbox will be checked. Unchecking it resets the color to its default value.
