"speeds" are set by values inside the () If you had this for zoom
0: (0), 30:(5), 60:(10)
then at frame 0 zoom would be 0 and it would increase to 5 at frame 30 and then increase to 10 at frame 60
For this you use the Translate X Change it to something like
0: (0), 25: (-5), 50: (+5), 75: (-5), 100: (+5), 125: (-5), 150: (+5)
Every 25 frames it alternates left and right translation/sliding.
For this you use the Rotation Y Change it to something like
0: (0), 30: (-1), 60: (1), 90: (-1), 120: (1), 150: (-1), 180: (1)
Every 30 frames it alternates left and right rotation/swinging motion
