Time shifting one channel

Hi,
I want to time shift one of the two channels so that they appear a little unsync.
How can I select just one of the channels (couldn’t find any option to do that) and use the timeshift tool on it?
Thanks/Brgds

You need to split the track into separate left and right channels, then you can work on either of the channels independently. See: http://manual.audacityteam.org/man/splitting_and_joining_stereo_tracks.html

Thanks
