Is there a way to move objects that reside across multiple frames
in one shot?
There is a small button located under the timeline, that will allow
you to select all of the keyframes you would like to move simultaneously
(hold the shift to select multiple frames). See image below.
Additionally, you will notice once you select this button, you
will have access to 2 black bracketed handles above your timeline.
By spanning these across multiple frame you will see how object
align themselves in relation to each other, even if they are not
normally viewed at the same time. Another perk of the bracketed
area, is that you can easily select the objects you wish to move,
by drawing a bounding box around them.
Test it out and play. If it is still not clear, feel free to write
me, I will try to explain in more detail.
