If Elements has got Lanes then it’s new in version 10, it certainly doesn’t have Lanes in version 9.
However, it wouldn’t, sadly, be the first time the Elements manual has referred to a feature that Elements just doesn’t have…this is probably why you can’t find the options. Comping is certainly not listed as an option in Elements in the Cubase 10 Comparison chart.
Going back to your original question, you can select different takes using the small downward pointing triangle that should appear in the middle of the audio that you’ve just recorded multiple takes of.
