Moving Clips to the Timeline
You can move a clip into the Timeline by double clicking on it in the Browser, which then will display the clip in the Viewer window to the right.
Then click on the clip in the Viewer and drag it down into the Timeline below. If it's an audio-only clip, you need to click on the tiny hand in the upper right of the Viewer above the waveform, and then hold down your mouse button and drag the audio clip down into the Timeline.
If the clip is just video, it will be displayed in the Timeline as just a green segment in the upper video track area.
If the clip is video with one or more audio tracks, it will be displayed in the Timeline as a green segment for the video, with the audio tracks displayed underneath as blue segments.
If the clip is just audio, it will be displayed in the Timeline as just a blue segment in the lower audio track area.
If you want to add a second clip at the end of the first one on the same track, double click on the second clip in the Browser, which will display the clip in the Viewer window to the right. Click on the clip in the Viewer and drag it down into the track on the Timeline to an area to the right of the existing clip.
If you want to add clips to different tracks in the Timeline, a good way to ensure you place them on the correct track (and don't accidentally overwrite an existing clip in the Timeline) is to select a destination track in the Timeline.
To do that, first double click in the Browser on the video clip you want to place on a new track, so the clip is displayed in the Viewer to the right.
Now look on the far left of the Timeline below at the second column in from the left. There you'll see gray buttons labeled V1 (for the video clip you've selected) and possibly A1 and A2 (the A1 and A2 buttons will appear if the video clip you've selected has audio attached to it).
Drag the V1 button to the new Timeline track where you want to insert the video clip (and drag the A1 and A2 buttons to new audio tracks if there's audio with our video clip).
Now drag the playhead in the Timeline to the point where you want the new clip to begin.
Then click on the clip in the Viewer and drag it to the right to the Canvas and release it (see also the section on Insert vs. Overwrite Edits). The clip (and any attendant audio tracks) will be inserted onto the new track in the Timeline and at the point you specified with the playhead.
