BAT Keyboard

The BAT Keyboard is made by Infogrip in the 1990s.

BAT Keyboard is a one-handed chorded keyboard.

You press 1 or more keys together to insert a letter or symbol.

There is a right-handed version and also a left-handed version.

It's supposed to solve the hand health problem of typical keyboard.

However, this is worse for your hand health, and super slow to type, because

1. It needs ~3 times more keystrokes for the same amount of input.
2. It's designed to be used by just 1 hand. This means, all the work will be put into 1 hand. (but you could buy 2 of them and use together.)
3. it's at least 2 times slower than touch typing using standard PC keyboard.
