How do I change the shortcut for lock screen? In macOS High Sierra, the new Lock Screen shortcut was added, but you can only use the shortcut  ^   ⌘   Q . I'd like to change it to something more Windows-esque, like  ⌘   ⌥   L . How can I go about this?
You can do this by following this webpage instructions :


Open System Preferences
Open Keyboard Preference Pane
Go to Shortcuts tab
Select "App Shortcuts"
Click "+"
Select "All Applications", "Lock Screen" and type your shortcut.
Quit System Preferences
