The HP Multi-Device Dual-Mode Keyboard with Palm Rest 585K (HP part BD5F7AA) is a full-size wireless keyboard for office and home users who work across more than one device. It connects through a 2.4 GHz USB-A receiver or by Bluetooth, and its multi-device support lets one keyboard switch between a desktop, laptop, tablet or phone. The full layout includes a numeric keypad and programmable hot keys, and quiet plunger-style keys keep noise down in shared offices. A separate cushioned palm rest (428.9 x 81.8 x 12.2 mm) sits in front of the keyboard to support the wrists in a more neutral position during long typing sessions. The keyboard runs on two AAA batteries and measures 428.2 x 121.4 x 21.9 mm, in black, and is not backlit. HP lists compatibility with Windows 10 and 11, macOS, Android and iOS. The box contains the keyboard, palm rest, receiver and warranty documentation. It is a sensible upgrade for anyone who wants a quieter, more comfortable keyboard that works with several devices without extra cables.
