Press Esc. There's a new "Operator" menu. From there you get the option to access your Focus, or Customize your Tenno :)

You can accumulate Focus by equipping a focus lense of your affinity on a fully levelled warframe or weapon. Then, once you go out with said piece of hardware... any affinity that would have gone to this weapon(which is now fully levelled up after all) will then go toward producing affinity for your focus.

Afterward, it's only a matter of accessing your Focus tree when inside your Liset and deciding where to spend your point in your focus ability. As first you unlock it as a fifth power that you can use no matter the warframe, then you seemt o be able to unlock additional branches which customizes/bolster that fifth power with additional benefits.

Naraimon's Focus ability for example seems to be at it's base a Mass Confusion type of move, but it can also be bolstered later with effects to bolster your allies and dishes additional effects on the enemies affected and so on.
