How to Select and Move Multiple Regions At Once
Selecting Multiple Regions
To select multiple regions of a track, first click on the Selector tool and then double click on a particular region to select it.
To select all the regions in the track at once, press Cmd-A (select all). You'll see the highlighted region extend to cover the whole track.
To select particular regions, hold down the shift key and click on the individual regions you want to select.
Moving Multiple Regions
To move the regions you've selected, first make sure you're in slip mode so you have the ability to shift the regions along the track.
Now choose the Grabber tool and then click on and slide the regions to where you want them on the track.
