There is no need to drag it to make it longer; just add something that plays longer, and it will automatically expand to accommodate it.  If you need to shorten it, start dragging it left, and while dragging press the left arrow key. It will jump to the end of the longest item that is not set to "play to end".

I've also found how to move a small item from one end to the other. For example, on a slide with a long video, where you have a button you want to show the last 10 seconds. Create the button to last for 10 seconds, start dragging it to\ward the end, and while it is moving, press end (or home, if you want to get it to the start).
