The KB file extension is used to depict keyboard script files created in the Borland C++ programming language. KB programming files are used to develop Windows-based software applications in the C++ code. C++ keyboard script files are used to enable executable functions using short-cut keyboard commands. KB files save time during development, since programmers don’t have to rely on the slower mouse functions. KB files don’t contain the actual commands used for keyboard short-cuts, but provide the data needed by the system to recognize the command and reference the appropriate script file. KB files can be accessed and edited at the script level within the related software application.
