The add-on uses the same hotkeys as the ones used at other places in Blender. By default this means the right-mouse button to select and G-key to move. Press the left-mouse button to confirm the movement or Escape-key to cancel. If you have changed your settings (e.g. left-mouse selection instead of right-mouse), the add-on will notice the changes and use your custom user preferences.

There are 3 modes in the add-on: Location, Speed and Timing.

  • Location: select a keyframe or handle and move it to change the location data of the object's animation path. Moving a frame automatically inserts a keyframe at that position.
  • Speed: select and move a timebead to change the speed-in or speed-out of the associated keyframe.
  • Timing: select and move a single keyframe to change the location of that keyframe on the timeline. Selecting and dragging a timebead moves all keyframes (except from the first and last one) on the timeline.

The Speed and Timing mode don't change the location of the object , only the speed. This holds true as long as the handles in the graph-editor don't overlap.

The motion trail can display different colours. Most interesting are the speed and acceleration gradients. Speed: blue is slow, red is fast Acceleration: green is positive, yellow is no acceleration, red is negative acceleration. Note: the colours are relative. So each is speed gradient contains both 100% blue and 100% red. Warning: At the start and end frames the gradients might be slightly off.
