Changing keyboard command for retrieving mouse cursor coordinates From what I've understood, ⇧ + ⌘ + 4 is the way one currently gets Mouse Cursor Coordinates in macOS. 

I use this combination for something else. Is there a way to change the keyboard command for retrieving the Mouse Cursor Coordinates? I tried looking in Settings > Keyboard > Shortcuts, but didn't find anything.

Perhaps then, the keyboard command could be edited with something like Karabiner?

If the keyboard shortcut is not editable, is there a good and simple stand-alone tool for retrieving coordinates?
That key combination is for producing a picture from a section of the screen selected by the mouse and so that key combination is already fixed. It just conveniently shows the co-ordinates when selecting.

Unless it is possible to edit in the kernel or somewhere...
