I prefer greyscale over inverting color when working in low light plus in general as its less strain on the eyes. But its too many clicks to toggle the settings. I am aware that to invert display color the shortcut is cmd+alt+ctrl+8. And open Accessibility options with cmd+alt+F5, but there is no grayscale in the options. Right now, I open Accessibility via spotlight, then choose display & toggle the check box. I am wondering of there is any shortcut key for that? If not, is it possible to make a keyboard shortcut.
