Google Now On Tap - Marshmallow's Best New Feature

How to toggle Google Now on Tap off and on - CNET. Now that I have a Nexus 6, I get updates to the OS as soon as Google makes them available. No more waiting a year for Verizon or another carrier to decide to let me have them. I have been impressed with Marshmallow, Android 6.0.1, and its introduction of the Google Now On Tap feature. While I can swipe the screen to the right to get all of my Google Now notifications, On Tap allows for contextual information by pressing the home button while in any app. Whatever is on screen then becomes a tool to bring up contextual choices, such as dialing a phone number. Once you start using it, it is addictive, and saves a lot of time.
