Question

My use case: I have a mouse with rocker buttons. I want to remap these buttons to be something else (forward and backwards). I know the button is recognized since it seems to allow for "open link in new tab" functionality when in Chrome - I know the button is sending some signal.

Using the keyboard viewer does not show what the button does. This is what I thought I would try first.

On Windows, using AutoHotKey a built in function basically gives a dump of all the scan codes windows receives to a console output. This would let me know exactly what button OSX is registering the keypress as.

What application for Mac will display scan codes (or keyboard/mouse input) in a fashion which will let me remap the input? It can be either a GUI application or a terminal app

Explanation / Answer

Install Karabiner.

Then use its EventViewer (look up the doco) to monitor the events your custom device fires.
