I know if I go to the first track and select my first element and then to my lowest track and select my last element and hold down my shift key, I select all the elements between. But sometimes that leaves out a bunch of elements. Then you have to select each remaining element in turn with the control key held down, to add them to the group. When you are dealing with a huge number of elements, that is a tedious and time consuming task.

Is there a "select all" function somewhere, that I am missing, that will allow me to do that task?
