Only3keys is a userspace application that allows you to type using only 3 keys!

• Did you ever think your keyboard is too large and useful?
• Did your keyboard burst into flames magically and destroy all but 3 keys?
• Maybe you're just super 1337 and you bought one of these!

Well don't worry! I got you!

Only3keys works by using 2 keys as 1 and 0, and a 3rd key for enter. Typing in binary, you can produce any ASCII code, and output it through a named pipe ("/tmp/only3keys" by default). The application on the other end of the pipe will happily accept it. Thats it! Additionally, because typing everything in binary is so excessively painful, certain features have been added to lessen the blow like responsive ascii charts that update as you type and "Double Tap" - allowing you to enter characters multiple times in few keystrokes (like "dd" or "1000000").

- limited to ascii (doesn't support: F1-F12, CTRL, ALT, Arrows, etc.)
    - does support ESC! Hello vi my old friend!
    - tools like emacs, screen, tmux, etc. that rely on CTRL, or other
    modifiers cannot and will not work. This will never be fixed, as it
    would require an entire rewrite of the project.

- must have window focus to capture keys.
    - this makes using a mouse near impossible. I recommend a tiling WM
    like i3, and just throwing the mouse right out the window.

- It's insanely impractical and near useless.
    - but hey, I did it for the lulz.
