scapple 1.40.2, Monterey 12.6.1
I often and for years now, select note → press Opt and double click on canvas outside note→ creates new connected note with arrow.
I recently migrated from Catalina to Monterey, the same keypress combination
1- generates a duplicate of the selected note (red arrow below)
2- creates a new connected note with arrow , that note being connected to the duplicate, not the original
I know that Opt is often used to duplicate as in drag and drop a duplicate with Mac OS
