Using Capitalization

The following are some general guidelines for capitalizing text within dialog boxes:

Dialog Boxes, Areas, and Column Headings

Use headline capitalization: capitalize the first and last words, and all other words except articles, prepositions, and coordinating conjunctions. However, if the dialog box is invoked from a menu (not from the Command prompt), its title should match the menu item.

Control Labels

Use headline capitalization for labels of control tiles such as buttons. Do not follow labels with a period. Follow the labels of a text box or a drop-down list with a colon (:). You may want to use sentence-style capitalization (in which you capitalize only the first word and proper nouns) if the label is lengthy or phrased as a question.

Prompts and Messages

Use sentence-style capitalization.
