Dragging either the vertical or horizontal handles will stretch the selected keyframes along the time or value axes. The horizontal handle corresponds to the XScale property, and the vertical handle corresponds to YScale.
The Pivot Type property controls the placement of the scale pivot point, which is denoted with a crosshair overlay on the graph. You can select the following options from it:
The Filter Tool contains various filters and commands with which you can Bake, Smooth, and perform other operations to your curves. To open the Filter Tool window, click the Filter Tool button in the toolbar.
When performing filter commands, the commands will only apply to the keyframes and curves you have selected in the graph.
Baking causes new linear keyframes to be created along your curve selection at a specified interval when clicking Apply.
When baking a curve section, only the section between your keyframe selections will be baked. In the above example you can see curve sections outside of the selection are not being baked.
Bake has the following properties:
The Euler filter is used to correct rotational frame jumps. Typically these can occur when working with imported raw motion capture data.
The Fourier Transform filter is used to smooth keyframes with a lot of divergences or noise between them. The smoothing effect is achieved without deleting keyframes, and is based on intelligent low or high pass smoothing with frequency parameters. Typically you would use this if you are cleaning up raw imported motion capture animation, or smoothing a noisy curve with many keyframes.
Select Fourier Transform (FFT) in the filters window to view its properties.
The type of Fourier filter to use.
In this example, a Butterworth filter type is being used to remove high frequency noise along a curve when clicking Apply.
The Simplify filter removes redundant keyframes based on a tolerance amount, while still maintaining the overall curve. You can also set the following properties to customize the Simplify operation:

View Modes
Opens a dropdown menu for the Curve Editor View Modes.
Zoom to Fit
Frames and zooms in on the selected keyframes. If no keyframes are selected, then all viewable keyframes within the Graph view will be framed. You can also use the F hotkey for this command.
Focus Playhead
Focuses the graph view on the Playhead without changing zoom level. You can also use the A hotkey for this command.
Zoom to Playback Range
Focuses the graph view so that all keyframes are visible, including the start and end frames of the sequence.
