+AutoHotInterception (AHI) allows you to execute AutoHotkey code in response to events from a *specific* keyboard or mouse, whilst (optionally) blocking the native functionality (ie stopping Windows from seeing that keyboard or mouse event).  
 In other words, you can use a key on a second (or third, or fourth...) keyboard to trigger AHK code, and that key will not be seen by applications. You can use the *same key* on multiple keyboards for individual actions.  
 Keyboard Keys, Mouse Buttons and Mouse movement (Both Relative and Absolute modes) are supported.

 4. Right-click `Unblocker.ps1` in the lib folder and select `Run as Admin`.  
   This is because downloaded DLLs are often blocked and will not work.  
   This can be done manually by right clicking the DLLs, selecting Properties, and checking a "Block" box if it exists.
