How can you delete trajectory dots? and how can you remove a movement entirely without deleting the whole object. I removed the timeline but the movement stays.. Maybe it's kinda vague what i mean... Hope you understand. Ren

The ( trajectory dots ) are key frames, to delete them, select the object, then use the animation VCR type buttons, ( Next Keyframe or Previous Keyframe ) will cycle through the keyframes. When it's at the keyframe you want deleted , press the delete keyframe button ( minus sign next to the Key button )

There's also a secret key-combination in the animationlab to delete all keyframe for one object. Unforunately I forgot it. Anyone else know it?

hold shift+ctrl+alt then click delete keyframe button. I think one of those keys is unnecessary but not sure which one

Deleting all keyframes is done by Ctrl,Shift,Alt keys while clicking the delete keyframe button. This trick deletes all keyframes, sky, materials, terrain,and translation of ALL objects in the scene.
