Is there a shortcut key to duplicate line in google colab?? If not how can it be implemented?

Question

I usually duplicate the line if i need to use the code same as the above line. I did not find the shortcut key to duplicate the line . I saw some posts to implement shortcut key to duplicate line but they are rather complicated and requires to run script every time.

Answer 1

For anyone still looking for a keyboard shortcut to duplicate lines in Google Colab,
Left_Alt + Shift + Down_arrow works for me!

Answer 2

edit: I've checked after time, now there is a shortcut is

shift + alt + arrow down or up
