In order to make commonly used menu options stand out more, simply go to “edit,” then select “menus.” From there, you can choose the look of menu options as you see fit. If you want to get rid of excess clutter, you can remove menu options completely.
If you want to get a bit more advanced, go to “edit” and select “keyboard shortcuts.” From there you can pick key combinations to do just about anything. Careful though – creating a new keyboard shortcut with an existing combination will overwrite the old one. In other words, make sure you’re okay with losing “ctrl + n” to make a new document if you decide you’d rather have that combo make something grayscale.
