Tap
Tap with the tip of the finger, not the fingernail. Tap fast and firmly, and then immediately lift your fingertip off the screen. Don’t bear down on what you’re tapping. Don’t wait for a response; the response comes after you lift your finger. Don’t linger on the gesture; a tap takes a split second to do.
Swipe
A swipe is a horizontal gesture, from right to left or left to right. Do it fast, do it lightly. In a swipe, your fingertip just skims the surface of the touchscreen.
Drag
Drag is the gesture you make for a slow scroll up and down, such as in a list, in a document, or on a web page. Slide your fingertip slowly along the
Drag and drop: Tap and hold the item. Wait until you get a visual cue that the item is ready to be dragged, and then drag it. Lift your finger to drop it. For example, a card in Card view is ready to be dragged when it
becomes transparent; an icon in the Launcher is ready to be dragged when a border appears around it.
Flick
This is a quick gesture, great for scrolling long lists, documents, or pages. Do it fast, do it lightly; as with a swipe, your fingertip just skims the surface. The faster you flick, the faster and farther you scroll up or down a list.
Close an application screen: To close an application screen in Card view, flick the card up toward the top of the touchscreen. This is called throwing the card off the top of the screen.
Delete a list item: In some applications, such as Email, Messaging, Music, and Bluetooth, you can throw a list item off the side of the screen to delete the item.
