how to overlap clips?

Hello,
I have just installed Audacity 2.0.6 in a MacBook Pro with Yosemite
My question is:
Can I overlap two clips in the same track for editing purposes? I have one track and then split it with “Command I”, suppose I have 2 repeated sounds and I want to overlap to have only 1, but would like to overlap and be able to move the boundaries of both clips to check if I am putting the wave of the second sound in the exact same position of the wave of the first sound. I have seen this being done in protools for instance but have not been able to do it.
I hope you can understand my question, english is not my first language and I do not know exactly how to explain it.
Thank you!
Andres

Unlike a video editor, Audacity can’t do that on one track. But we can do it on two tracks.

Tracks > Add New and create a new blank track underneath the first one. Then copy and paste your secondary sound into the second track.

Then use the Time Shift Tool to push the second sound so it starts when you want it to (attach).

Use the MUTE and SOLO buttons to turn each track on and off as you need.

When you Export your show, Audacity will make one song out of your production, no matter how many tracks you have.
