	Name	Description
int32	DuplicateKeyframe ( int32 KeyIndex, float NewKeyTime, UInterpTrack* ToTrack )	Duplicates the given key.
bool	GetClosestSnapPosition ( float InPosition, TArray< int32 >& IgnoreKeys, float& OutPosition )	Gets the position of the closest key with snapping incorporated.
FColor	GetKeyframeColor ( int32 KeyIndex )
int32	GetKeyframeIndex ( float KeyTime )	Get the index of the keyframe with the given time.
float	GetKeyframeTime ( int32 KeyIndex )	Get the time of the keyframe with the given index.
int32	GetNumKeyframes()
void	GetTimeRange ( float& StartTime, float& EndTime )	Gathers the range that spans all keyframes.
float	GetTrackEndTime()
void	RemoveKeyframe ( int32 KeyIndex )	Removes the given key from the array of keys in the track.

EInterpCurve...	GetKeyInterpMode ( int32 KeyIndex )	Get the interpolation mode of the specified keyframe.
float	GetKeyOut ( int32 SubIndex, int32 KeyIndex )	Get the output value for the key with the specified index on the specified sub-curve.
int32	GetNumKeys()	Get number of keyframes in curve.
int32	GetNumSubCurves()	Get number of 'sub curves' in this Curve.
void	GetOutRange ( float& MinOut, float& MaxOut )	Get overall range of output values.
void	GetTangents ( int32 SubIndex, int32 KeyIndex, float& ArriveTangent, float& LeaveTangent )	Get the incoming and outgoing tangent for the given subcurve and key.
int32	SetKeyIn ( int32 KeyIndex, float NewInVal )	Set the input value of the specified Key.
void	SetKeyInterpMode ( int32 KeyIndex, EInterpCurveMode NewMode )	Set the method to use for interpolating between the give keyframe and the next one.
void	SetKeyOut ( int32 SubIndex, int32 KeyIndex, float NewOutVal )	Set the output values of the specified key.
void	SetTangents ( int32 SubIndex, int32 KeyIndex, float ArriveTangent, float LeaveTangent )	Set the incoming and outgoing tangent for the given subcurve and key.
