When you click on (or tab to) a course, it should be selected, instead of opened. A "selected" course then displays a "handle", on the left, and a "info" button, on the right.
You should be able to cmd/ctrl-click to do dis-contiguous selections, and shift-click to make selection ranges.
Once a course or group of courses is selected, you can either drag it by way of the handle on the left, or expand the info panel by clicking the info button on the right. Either action will operate on all selected courses at once.
You can select text on the course by clicking and dragging on the course itself.
