if I click on one track to highlight it and put the curser at the begining of the track it changes into a horizontal bar with an arrow pointing left and right.

You have got the “Multi-Tool” selected http://manual.audacityteam.org/manual/help/manual/man/tools_toolbar.html

Also there is a “Pseudo Stereo” plug-in available here: Pseudo-stereo effect
