I sometimes accidentally minimize the window for Quick Edit Pro. I get the smaller variable size and position window that I can intentionally create for some apps by long press of return button (Android 5, Samsung GN3).

But Quick Edit Pro does not appear in the list I get when long pressing.

What kind of swiping movement do I sometimes perform unintentionally in the upper part of the screen, that minimizes to this useful window.

I have tried many times but can not repeat it intentionally.
