Input Leap is software that mimics the functionality of a KVM switch, which
historically would allow you to use a single keyboard and mouse to control
multiple computers by physically turning a dial on the box to switch the
machine you're controlling at any given moment.

Input Leap does this in software, allowing you to tell it which machine to
control by moving your mouse to the edge of the screen, or by using a
keypress to switch focus to a different system.
