How to insert space or make a gab between many joined stripped pieces of Audio VSE? My question is the reverse process of this question: How to automatically join stripped pieces of video?

I have many pieces of audio or clips that are joined together (eg: 20 clips). I need to make some space/gap between the fifth and the sixth clips so that I can insert another clip.

I downloaded the power sequencer Plugin but I'm not sure if it can do it or not. 

What's the easiest way to do it?
There are at least two fast methods:

First method

Inside the VSE, deselect all strips then, press b and drag your mouse to box select the strips you want to move. When you have selected them, press g to grab all of them and move them by the desired amount with your mouse. Finish with LMB.

Second method

Inside the VSE, place your cursor inside the strip after which you want to insert the gap with LMB. Then select Strip -> Insert Gaps or press Shift+= and it will insert a gap after the current strip. This is actually the reverse of the method mentioned in the question you linked.

Hope that helps.
