The '''Infogrip BAT Keyboard''' is a [[:Category:Chorded keyboards|chorded keyboard]] by [[Infogrip]]. Characters can be entered by pressing a combination or a sequence of combinations of the seven keys.

==Variants==
Early versions connected to a computer by a serial interface (RS232).<ref>Buxton Collection — [http://research.microsoft.com/en-us/um/people/bibuxton/buxtoncollection/a/pdf/BAT%20brochure.pdf BAT brochure]</ref> Special software had to be run in order to use the keyboard. In 1994, the keyboard was fitted with both an [[AT]] and an [[ADB]] connector; no special drivers were necessary for it to operate.<ref>Buxton Collection — [http://research.microsoft.com/en-us/um/people/bibuxton/buxtoncollection/a/pdf/BAT%20newsletter.pdf BAT newsletter]</ref> The current (as of Nov-2013) version of the BAT keyboard has an [[USB]] interface.
All versions were/are available as a left-hand version and a right-hand version.

==Usage==
Characters are entered by pressing and releasing a combination of its seven keys: four finger keys and three thumb keys. Ordinary letters can be entered by combinations of the four finger keys and the central, grey thumb key. E.g. pressing those five keys at once and releasing them sends the character 'o'. The remaining two thumb buttons, red and blue colored, enable entering numbers, interpunction, function keys and modifiers like shift, alt and control. Usually, modifiers are entered using the sticky key principle: for instance, once the shift command is given (blue thumb key pressed and released), the next character will end up as the shifted version.
The BAT keyboard can be configured by software. Additional chords as well as macros can be created .

==Switches==
The BAT keyboard is equipped with modified [[Cherry MX Black]] switches whose springs have been replaced for a much lighter version. The actuation force is even lower than that of [[Cherry MX Red]] switches.

==Trivia==
The name stems from the city in which [[Infogrip]] was founded: [http://www.openstreetmap.org/#map=12/30.4448/-91.1276 Baton Rouge, LA].
