re: Ctrl-Alt click on the close icon of any window and it'll close all windows
This was introduced in 4.02 i.e. it is not in 3.70
I do remember discovering the "Shift-double click with the Select button on a directory icon, closes al sub dirs' but then couldn't remember the keyboard/icon/button required, thanks for the reminder. Interestingly the directory being clicked on must be open but lower directories do not need to be open for all even lower ones to be closed!
