Once you have a clips in the Timeline, you can move them to the left or right by just clicking and dragging them.

You also can shorten clips in the Timeline by clicking on the edge of a clip and dragging it in.

Similarly, if you have a clip you shortened in the Source pane before putting it in the Timeline, you can lengthen it in the Timeline by clicking on the edge of the clip and dragging it out.

If you have a clip with both video and audio tracks, and you want to change one track without affecting the other (such as deleting the audio track), right click on the clip and select Unlink in the drop-down menu. You now can move the video and audio track clips independently of each other.

By default, the Timeline is set up so that adjacent clips "snap" to each other, which makes it easy to align them without having one clip accidentally overlap the other or having an empty space between the clips.

But if needed, you can turn off snapping by clicking on the Snap icon, which is in the top left of the Timeline, above the labels for the video tracks. If you pass your mouse cursor over the icon the word Snap will appear.

If you want to delete a clip on the Timeline, just select it and press the delete key on your keyboard.
