Create Keyboard Shortcut for Anything on a Mac
Click the Keyboard Shortcuts tab and then the plus sign. This will provide you with a little panel that will let you override a keyboard shortcut for a specific application or all applications. All you have to do is type in the exact menu title of the command in the panel and the new keyboard shortcut you want to assign to it. When you’re done, click add, and it’ll immediately be the active keyboard shortcut for the command you specified.
