From the developer:
SkookumMorse is a CW keyboard application that leverages the K1EL WinKeyer USB to send morse code. You may find it useful for general operating with computer-generated CW, or for setting WinKeyer standalone mode parameters. You may need to install the FTDI serial device driver; get the latest version directly from the FTDI web site.
You may want to check out more Mac applications, such as Auto-Tune Evo VST, Automize7 or Bulk Image Resizing Thing, which might be similar to SkookumMorse.
