The Angle settings allow you to edit the angles of a selected tangent in a keyframe, using degrees. The angle of left and right tangents are unaffected by previous and next keyframes when tangents are edited, and become fixed.
The Angle settings consist of fields, Reset buttons, and a Link button.
Angle settings A. Angle for left tangent B. Reset Left Angle/Auto option C. Link/Unlink Left & Right Angle/Auto option D. Reset Left Angle/Auto option E. Angle for right tangent
Allow you to change the angle of the tangents for a selected keyframe to specific degrees. The Angle field on the left affects the left tangent, and the Angle field on the right affects the right tangent. The values of these fields depend on whether Visual or Exact is selected in the Tangent menu.
The angle of a selected left and right tangents of a keyframe are not affected by neighboring keyframes. Instead, the values in the Angle fields are negative or positive in relation to the selected keyframe, as if the keyframe is at coordinates (0, 0) on a Cartesian plane.
When you set the angle of a tangent to:
Allows you to reset the Angle values for the right and left tangents of a selected keyframe to zero (B and D in the figure above). Tangents set to zero are flat, and display horizontally.
When the Link/Unlink Left & Right Angle/Auto option next to the Angle fields is active, you can modify the angle of both left and right tangents at the same time, whether or not the tangents are broken or unbroken.
When the Break option is active (Break option), you can modify or reset the angle of each tangent separately when the Link option is disabled, or by dragging a tangent handle.
