what is the best way to duplicate a line?

[Yellow-Subroutine]

Hi,

I am just editing a table and would like to add a new row and for that I would like to simply duplicate a line.
There is a button to delete a line but there does not seem to be an elegant way to duplicate a line - or am I simply missing it?

How do you do it?

There is an option to select the current line(s) under the special key action. It's a little buried.
