MultiMod is a simple App to provide a missing feature to Mac OS.  Normally, when more than one keyboard is connected to a Mac, modifiers only have an effect on keys on the same keyboard.  MultiMod alters this so that a modifier key (shift, command, control, alt, function) pressed on one keyboard will modify key presses on all keyboards.

This is essential to make things like ergonomic foot pedals that function as modifier keys work properly on a Mac.

MultiMod should work on any device, wired or wireless, that connects as a standard keyboard.  It has been tested extensively with Kinesis Ergo brand foot switches.

 MultiMod sits unobtrusively in your menu bar, and uses minimal system resources.
