Click Options in the function bar below the main menu and select Global Options - Keyframe Editor on the left.
Here you can make a few settings for In-Screen Editing and the Keyframe Editor.
In this field you can enter the snap radius for the screen object handles. The default setting is 5 pixels. The higher the value, the higher is the "magnetic effect" of the handles on the mouse pointer.
Here you can define the location where the Keyframe Editor is to appear when highlighting a control track.
Without any checkmark, the Keyframe Editor is opened at the bottom of the timeline window.
With a checkmark next to Open Keyframe editor beneath the timeline object it opens directly below the object whose control track was highlighted and maintains its position until it is closed.
With an additional checkmark next to Update position with object selection it keeps jumping to the object whose control track has just been highlighted. You only need to close it when an object is not visible.
If you don't want to edit the keyframes in combined control tracks directly in the object, you can place a checkmark next to Use keyframe editor for combined control tracks. This may be useful if you tend to crossfade images and videos in a track as it allows also the keyframes in the crossfade area to be edited.
