Dave T2 has a great suggestion. As an alternative, you can highlight the section you want and then cycle the Tab key for video, audio, or both. From there, just hut the "a" key and your clip will go to the timeline at the indicator line.
And another way: when you drag, instead of dragging in the (vertical) middle section, drag in the top or bottom section to get just the video or audio. The Tab key cycles this after a drag.
