# Capitalization UI guidelines for using title and sentence capitalization in various contexts. ## Title > The current Windows guidelines use sentence capitalization for actions. Some Microsoft products still title-capitalize actions according to the previous guidelines. macOS also title-capitalizes actions. Since IntelliJ IDEs are cross-platform, we use title capitalization as well. > {style="note"} Use for: * Actions in buttons, menus and tooltips * Headers in tables, popups, message boxes and dialogs * Headers of UI control groups Do **not** use for: * Actions in links * Actions in the popup on Alt+Enter: quick-fixes, intention actions, and others * Headers in notifications ### Rules {id="rules_1"} Always capitalize the first and the last words. Capitalize the words in-between except: * articles: *a, an, the*, * coordinating conjunctions: *and, or, but*, * prepositions of four and fewer letters which are not a part of a phrasal verb: *in, with*. In hyphenated phrases, capitalize all nouns, adjectives and adverbs: *Auto-Indent, Command-Line Launcher*. Do not capitalize articles, prepositions and conjunctions: *Side-by-Side, Drag-and-Drop*. ### Examples {id="examples_1"} - _Compare With…_ — the short preposition *with* is capitalized as the last word. - _Compare with Latest Repository Version_ — *with* is not capitalized when in the middle. - _Check Out from Version Control_ — *out* is a part of the phrasal verb *check out* and is capitalized. ## Sentence Use for: * Labels of UI controls: text boxes, checkboxes, radio buttons, combo boxes, etc. * Items in combo boxes, lists, trees and tables * Links * Actions in the popup on Alt+Enter * Header and body text in notifications * Body text in error messages, tooltips, status descriptions and any kind of instructions ### Rules Capitalize the first word in a sentence, proper nouns and adjectives, and abbreviations. ### Examples - _Control+Shift+F_ — keyboard button names are considered proper nouns. - _Accept the terms of the License Agreement_ — License Agreement is a proper noun. - _Side-by-side layout_ — only the first word of a hyphenated phase is capitalized.
