Hi @Anonymous!
Animations play a "frames per second" fps. To decrease the speed of an animation, you need to increase the number of frames between keys. So if your time line is 30 frames, and you render at 30 fps, you get a 1 second animation. Change to 15fps and you get a 2 second animation, etc.
The timeslider playback is not the same as render playback. Adjust your timeline to increase your frames and scale your animation accordingly to get your timing where you want it. Work backwards - figure out how long you want the animation to be, and at what point in that timing you want the action to occur; add enough frames for that timing and move your keys to those milestone times within.
Hope this helps,
Kenny
