How to push the button underneath

[Romanoff]

Hello,
I have a second question: How do you use the second row of buttons under the fingers on the Cyborg? The first row is like the Compact and Classic and easy to reach. How is this operated by the first finger limb?
Unfortunately I haven't found anything in the gallery or on instagram, so a picture or even a video would be really great.
Thanks

I lift my finger out, and then pull it with the tip of my finger. I normally reserve those buttons for stuff I'm not going to use very often.
