Repositioning Items
To reposition an item or group of items already in a timeline track, begin by selecting the item or group. Then:
enter the start time in the Item field,
drag and drop the selection within its track or, in the case of channel animation clips, onto another channel track.
In the case of a multi-item selection, entering a value on the Item time zone will align the activation of all of the selected items at the new time value.
A magnet effect allows you snap both keys and clips to the beginning and the end of the timeline range. This magnetism also helps you to position clips one after another with no pause in between. Additionally, you can use it to align the activation times of elements in one track with elements in other tracks.
