 # Description: Open selected files in nuke one by one or in oneshot
-#              Tip: keep pressing "Enter" to open files one by one
 #
-# Note: Uses nuke by default, easy to replace with preferred opener
-#       nuke is invoked once for each file in a loop
+# 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
