Capitalizing texts in user interface

Question

I\'d like to ask you if there is a reason to capitalize all items in menus, etc in application user interface, for example

• File->Page Setup
• Edit->Select

Answer 1

Because menus are usually formatted like titles in English. In a title, the first word is always capitalized, as well as any nouns, adjectives, verbs, adverbs, and pronouns. If they are not the first word in the Title, articles and prepositions are not generally capitalized.
