In the Waveform tab is there a keyboard shortcut to unselect the selected area?

Hi there,

in my on going project I have to do a lot of copy past action.

The problem is after pasting some sound to the audio file I want to move on to listening end editing but the selection stays there and I have to unselect it with my mouse by clicking somewhere else.

If there is a way to solve that small issue that would be a life saver to me.

Thanks in advance.
