Typing at a good speed and that too without making any errors is an art, for you need professional training and a good practice over the keyboard to do it. At least, it‘s not my cup of tea, as I literally have to hunt for keys while typing something on my PC, which of course hampers performance at work. No need to worry anymore, as latest wearable keyboard, attachable to PC via USB, is ported to at90usbkey demo board that can really help you overcome your small but offensive quandaries. The new wearable keyboard, an advanced version of ATtiny2313 connected to PC via PS/2 and Attiny2313 microcontroller, can generate all common characters with few keys that are pressed in groups. I am not sure about full-screens, but it may prove a boon for small systems such as portable computers and palmtops.
