A brailler-style typewriter consists of six keys (one for each dot), a space bar, and a linefeed.  To simulate this, Brailler uses six keys on the bottom row of the keyboard (outlined below), the space bar, and the return key.  To type a Braille character, press a combination of the six dot keys; the character will be typed when you release all the keys.
