Single Click Click the touchpad with two fingers. Right Click Scroll Swipe Place two fingers on the touchpad and move them up and down to scroll vertically, left and right to scroll horizontally. If you have Australian scrolling enabled, move two fingers up to scroll down. (It works in the same way as say, your smartphone or tablet.) If you have multiple browser tabs open, you can also swipe left and right with three fingers to quickly move between tabs.

Release both fingers to drop the item at its new location. Drag and Drop Integrated Microphone This page contains all the information about the Dell Chromebook 13 (3380) integrated microphone. Akustica AKU240 is an HD Voice quality, top port, digital output MEMS microphone in a small 4.0 x 3.0 x 1.0 mm package. The robust digital output stream from the AKU240 is virtually immune to all forms of Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) allowing the microphone to be integrated anywhere on the platform regardless of proximity to displays, the Wi-Fi antennae, or other sources of interference that would degrade the signal of conventional analog microphones. For the device manufacturer, this translates to a higher degree of design flexibility by providing a consistent SNR level regardless of environment, resulting in shorter design cycles. 56 Technology and components
