2.3.0 "Mix" function???

When I edit audio files on my Korg KRONOS, there is a function called “mix” where I can copy a section and instead of inserting it, I can layer it over wherever I set the cursor.

Does Audacity have something like that? I can’t seem to find it if it does.

“Tracks menu > Add New > Mono / Stereo Track”
Then paste into the new track.

Alternatively, select the part that you want to duplicate, then “Ctrl + D” (or “Edit menu > Duplicate”).

Not exactly how it works on the Kronos, but that does help! Thanks!
