Hi Shubham,
The user-interface (nonprogramming) way to do it is to Ctrl-click to select that item, then perform the task on the selection.

If you really need to look at the code, it may be very complicated, and somebody else would have to respond since I don't know the answer.

I hope this helps,
Elaine
