You can type on FTWT4A using your device’s built-in touch-screen keyboard, but it’s much faster to use an external keyboard and type on real keys, just as you would on your desktop computer.
Here are some recommended keyboards for use with the FTW Transcriber, along with links to purchase. Most of the links will enable shipping to anywhere in the world.
IMPORTANT: before purchasing a Bluetooth keyboard, please ensure it is compatible with your device.
Perixx PERIBOARD-805L Bluetooth Folding Keyboard
Because the Periboard folds, there’s no vulnerable 
keyboard face to damage while it’s being carried around, and unlike most external keyboards it’s compact enough to fit easily into a pocket. It comes in two sizes, 16 cm and 14.5 cm in length.
The fact that the keyboard is designed to fold means that it’s effectively split into two halves with an unused space between. For that reason, it will be much more suitable for touch-typists – if you’re used to moving all the fingers of both hands all round the keyboard, you’ll find this one confusing.
Perixx PERIBOARD-804
The Perixx Periboard 804 is compatible with 
Android and Apple devices, though not Windows PCs, but works fine with FTWT4A. It’s easy to type on, and is available in both UK and US keyboard layouts.
