Select multiple clips and drag, deselect after drop

When I select multiple clips and drag (move) them to a new position, the selection will be deselected when the move is done. How to keep the selection after drag and drop? Sometimes I need to further move them and the selection need to be repeated many times.
The second question (or suggestion) is: If I directly drag a clip before I select it, there is a lag period and makes the cursor move earilier than the clip. The faster you do the drag, the further the distance between cursor and clip. If I drag the clip after select (click) on it, the cursor will stay in sync with the clip. How to make it in sync in both ways?

And for the second thing, it is what it is. You already know the answer.

Thanks for the quick reply!
