# Description: Open selected files in nuke one by one or in oneshot
#
# Notes: 1. Opens the hovered file if the selection is empty
#        2. nuke is the default, set OPENER below for custom
#        3. Opener is invoked once for each file in a loop
#        4. Keep pressing "Enter" to open files one by one
#
# Shell: bash
