Elements 9.5: How to playback left or right channel only?

I’m trying out WaveLab Elements 9.5, and I’m a bit stumped. I can select a portion of the left or right channel with the mouse, but when I attempt to play the selection, it plays back both channels, even though only channel is clearly selected.

What am I missing?

thanks

If you want to play only one channel, which is not so common, use the playback tool. Shortcut it to press Alt and move the mouse over a channel edge.

Didn’t quite understand what you were saying, but I figured it out: Hold ALT and then hold down the mouse button on the L or R section of the waveform that I want to play. Thank you
