How to select more than one track

Hi,

I'm new to Audition and I can't figure out how to select more than one clip/track in Audition 2014 multitrack view.  I tried holding down shift and/or control and clicking on more than one clip or track, but that doesn't work.  I have separate clips on the different tracks and I'd like to be able to select them all the move them the same distance.  Is there any way to do this?  Thanks. 

Also, is there anything like a "missing manual" anywhere online for Audition?  All I can find are specific tutorials on specific topics.  Thanks again.
