How can I view a list of system and application keyboard shortcuts? I often find applications that use conflicting keyboard shortcuts and it is difficult and time-consuming to determine which shortcuts are conflicting.  Are there any applications or commands that can show in a human readable format all active shortcuts?

EDIT 1: This is NOT a duplicate of this question.

The suggestions to use KarabinerEventViewer simply do not display the application/command called on a given key combination.

The exact combination that I cannot determine is CMD+OPTION+/.

EDIT 2: Why is CheatSheet not suitable?

It simply displays an overlay with the keybindings for the application in focus.  It also doesn't help for applications without a window (background apps).  This doesn't help my use case as the keybinding I am debugging doesn't launch an application window.  Think about how Spotlight or Alfred renders a search component for a given key combination.
Try the utility CheatSheet. 

It appears that after downloading the utility, press the Command key a little longer than usual and you are then presented with the currently active keyboard shortcuts. Check out the software below
