Set focus to new window when turning on dual display

How do i do this:

When presses toggle dual display, the focus needs to switch to the lister on the right.?

thanks in advance

Set FOCUS=Right

OR

Set FOCUS=Right SOURCE=Right

Or:

Set DUAL=Toggle,Source

(No one expects the Spanish Inquisition!)

Or:

Preferences - Listers - File Display: Set new window to source when switching to dual file display.

Thanks a lot fellas, leo what is that youtube link? :smiley:. Is there a message for me in it ?

YouTube video was just to explain the joke in case you hadn't seen Monty Python. :slight_smile:

It's a famous comedy sketch where someone lists things and then keeps realising there's one more thing to add to the list.
