If your insert at a split point, the clip will drop in and ripple those to the right. Position the cursor at the split, right-click the bin clip, PLACE ON SEQUENCE AT CURSOR, or drag it there.
If you insert in the middle of an existing clip, that clip will be split and ripple clips at its right.
To drag a group of clips to the right, click the first clip, hold down <shift>, click the last clip. Drag. Leaves a gap. If the clips snap, hold down <alt> while dragging.
The same applies to text or audio clips.
