How to get the "Navigation menu" on Dimka skin?

I'm playing with primo 9.6.5.211211 using the "diMkaWA_P156_default" skin.
I can't find the way to go back to the "Navigation menu", the one that shows when program starts.
Alternatively, I just need the on/off button to turn the program off after use.

Thanks.

long press to lower right corner

You can also configure one of the Quick Menu buttons to be a "Power Off" button.

Thanks for the replies.
The first one was tested right away. What a relief :)
About the "Quick Menu", it will take me awhile to get use to it and to get full control of the way it works.

The reason for me to use this skin is because it's the only way I can use the camera alerts with audio voice/sound. I couldn't make it work with the default skin. But it's ok, I can live with it.

Thanks.
