Hmm, does not work for me. After I select an entire line using SHIFT-ALT-L (not CTRL-ALT-L as I erroneously wrote), SHIFT-downarrow/SHIFT-uparrow do not select additional entire lines?
Try pressing Shift+Alt+L, releasing Alt and L, and then pressing the down arrow while you're still pressing the Shift key.
