For heavy-duty writing on the go, regular keyboards are too big, while touchscreen keyboards are too small. But Microsoft (MSFT) is betting that is new, foldable keyboard will be just right.

Microsoft unveiled the Universal Foldable Keyboard on Monday, a thin, lightweight keypad that folds down the middle. Unfold the keyboard and it automatically powers on and connects wirelessly to Bluetooth-enabled phones or tablets. The battery lasts upwards of three months on a single charge, according to Microsoft.

The keyboard will go on sale at the Microsoft Store and various retailers this July for $99.95.
