The tool window consists of the various blending modes, additional features, presets and the slider used for favouring the pose before or after.

Icon	Mode	Description
	Between	Interpolates between two adjacent keys, ignoring the current key.
	Towards	Interpolates towards two adjacent keys based on the current key.
	Average	Interpolates towards the average value of the selected keys.
	Curve	Interpolates along the curve formed by the two adjacent keys' tangents.
	Default	Interpolates towards or away from the default value of each attribute.

Icon	Name	Description
	Overshoot	Allows the interpolation to move past the target.
	Key Hammer	Adds a key for every attribute for any key on selected objects. The manual equivalent method would be to go to the first key and press S, go to the next keyframe and press S, go to the next keyframe and press S etc. for every keyframe.
	Special Tick Color	Sets the current frame, selected keys, or time range to the special keyframe tick color.
	Normal Tick Color	Sets the current frame, selected keys, or time range to the normal keyframe tick color.

A few additional options can be accessed by right-clicking anywhere in the window.

The toolbar and preset button can be shown or hidden for a smaller window.

Keys can automatically use the special tick color. This applies to both new and existing keys. Caution: Modifying key colors cannot currently be undone! Note also, that due to a limitation in Maya, the selected range in the Time Slider panel will be lost when modifying the key color.
