+      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.
