+Smooths the selected keyframes using a Gaussian kernel. It can handle gaps in the keyframe data.
+The operator is modal with a blend factor, making it possible to tweak the strength of the filter.
+
+Factor
+   A blend factor from original to filtered curve.
+
+Sigma
+   The shape of the gaussian distribution. Lower values mean a sharper curve, giving keys that are close to each other more weight.
+   A high value behaves like a simple average filter.
+
+Filter Width
+   A wider filter looks at more keyframes, producing a smoother result.
+   At a size of 1 the filter only looks at the keyframes to the immediate left and right for a weighted average.
