Samsung has announced a new wireless keyboard accessory that can be paired with up to three devices (including Galaxy phones, Galaxy tablets, and laptops) and switch between them seamlessly.

The Smart Keyboard Trio 500 was first introduced by Max Jambor on Twitter. The keyboard features DeX shortcut keys that quickly activate desktop mode on Galaxy phones and tablets; DeX is Samsung's attempt to unify the mobile and desktop experience, similar to other drop-in systems we've seen fail for years It is. When combined with a monitor, DeX becomes a desktop interface that runs from a cell phone or tablet. This is a great idea, but has yet to gain widespread adoption.

The real appeal of the Smart Keyboard Trio 500, besides its name, is its ability to seamlessly switch between the three devices. While it may be difficult to envision a real-world use case, someone will love this feature. Switching between devices is done by pressing the appropriate shortcut key in the function column.

The keyboard also has an app key to access frequently used apps. This requires One UI 3.1 after the March patch, so keep that in mind.

The keyboard comes in black and white and is powered by AAA batteries. This is both a good and a bad thing, depending on how you look at it. On the one hand, it cannot be easily recharged, but on the other, if the batteries run out while you are out and about, you can simply replace them.

As of this writing, there is no word on pricing or availability of the Smart Keyboard Trio 500, but we expect Samsung to mention the product at its Unpacked event next week on the 28th. We think Samsung will highlight its new laptops, Chromebooks and tablets, but do not expect to hear about the handset.
