Keyboard shortcuts of XPS 16 9640

NOTE:Keyboard characters may differ depending on the keyboard language configuration. Keys that are used for shortcuts remain the same across all language configurations.

Some keys on your keyboard have two symbols on them. These keys can be used to type alternate characters or to perform secondary functions. The symbol that is shown on the lower part of the key refers to the character that is typed out when the key is pressed. If you press shift and the key, the symbol that is shown on the upper part of the key is typed out. For example, if you press 2, 2 is typed out; if you press Shift + 2, @ is typed out.

The top row of the keyboard is a capacitive touch panel. The fn mechanical key toggles between the keys F1-F12 and keys for multimedia control. Releasing the fn key switches back to the previous mode.

Pressing the fn key and the esc key locks the "mode" of the capacitive touch panel. If the computer restarts, the default mode is the last mode set by the user before the computer is restarted.

The fn key is also used with selected keys on the keyboard to invoke other secondary functions.

Dell low blue light display

WARNING:Prolonged exposure to blue light from the display may lead to long-term effects such as eye strain, eye fatigue, or damage to the eyes.

Blue light is a color in the light spectrum which has a short wavelength and high energy. Chronic exposure to blue light, particularly from digital sources may disrupt sleep patterns and cause long-term effects such as eye strain, eye fatigue, or damage to the eyes.

The display on this computer is designed to minimize blue light and complies with TÜV Rheinland's requirement for low blue light (hardware solution) displays.

Low blue light (hardware solution) mode is enabled at the factory, so no further configuration is necessary.

To reduce the risk of eye strain, it is also recommended that you:

Position the display at a comfortable viewing distance between 20 and 28 inches (50 cm and 70 cm) from your eyes.
Blink frequently to moisten your eyes, wet your eyes with water, or apply suitable eye drops.
Look away from your display, and gaze at a distant object at 20 ft (609.60 cm) away for at least 20 seconds during each break.
Take an extended break for 20 minutes every two hours.
