Use sentence case for menu items
Following Adobe's UX writing style, write menu items in sentence case unless they contain words that are branded terms.
Ellipses in menu commands
Don't end a menu command with an ellipsis (…) unless it requires additional input to complete the action, typically in a dialog.
Using descriptions in menu items
Only use descriptions in menu items when the information will help a user to decide which action to take from the menu. Don't overload menu items with repetitive information or with promotional calls-to-action.
