Typing on a GKOS keyboard

for typing letters and numbers, maximum 2 simultaneous key presses are needed per hand but whenever one hand presses two keys , the other hand needs to press one key or no key at all. The Letters A to F are just single keys and the rest needs the press of simultaneous keys. There are standards where thumbs can be used to type by suitably modifiyng the implementation. The X, Y, Z. letters forms the most difficult combination because three keys must be pressed simultaneously.
