Select the events you want to move by holding down the ctnl key and left clicking the events you want, and you can drag them all at once. If you hit the “G” key while they’re all selected, that groups them so you can move them all by just dragging any of the grouped events. To ungroup them, select them all again or just the ones you want to ungroup and hit the “U” key.
Hope this helps, Danny Hays
