"Practice with computer": How to switch sides ?

While in analysis board, when I turn on the (super cool) "Practice with computer" feature, how can I switch side ?

Please correct me if I should post somewhere else - where is the right place to post site technical questions ?
(I tried to google it first of course....)

Flip the board so the colour you want to play as is closer to you, then click "Practice with computer"

Thanks @mcoombes314 !
I feel stupid for not figuring this out on myself. I assumed the flip board is only about the visual presentation.
