To type an ellipsis, use three periods without spaces. In the Menu Title field, type the menu command, for example, Build Standard-Sized Previews. You must type the command exactly as it appears in the menu, including ellipses (such as Synchronize Folder…) and any other punctuation.If it doesn’t show up, scroll down to the bottom, select Other and navigate to Applications > Adobe Lightroom > Adobe Lightroom.app. Select Lightroom in the Application pop-up.
On a Mac, the easiest way to change a keyboard shortcut is to use the operating system keyboard preferences. If you’re using the English version of Lightroom with another language keyboard, some of the keyboard shortcuts might not work.
