Description

Logitech Wireless Touch Keyboard K400 is a compact wireless keyboard designed to provide keyboard and pointer control from a convenient distance. The integrated touchpad allows users to move the cursor and perform supported touchpad gestures without requiring a separate mouse.
Logitech’s documentation identifies the K400 as a distinct model from the later K400r, with its own hotkey and touchpad functionality.
The keyboard connects through Logitech’s Unifying USB receiver using 2.4GHz wireless technology. The original K400 setup guide shows the receiver being connected to a computer’s USB port, while the keyboard uses an on/off switch and two AA batteries.
The integrated touchpad provides convenient cursor control, with Logitech documentation identifying tap-to-click, double-tap-and-drag and vertical scrolling among the supported gestures for the original K400. Dedicated controls also provide quick access to functions such as mute, volume down and volume up.
The K400 is particularly suited to situations where a separate keyboard and mouse would be inconvenient, such as controlling a computer connected to a television or using a compact wireless input device from a distance. Compatibility and operating-system support should be checked against the exact K400 SKU and the host device before purchase.
