# Capitalization

> For the complete documentation index, see [llms.txt](https://plugins.jetbrains.com/docs/intellij/llms.txt).

## Title

> **Note:**
> 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, they use title capitalization as well.

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

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

* 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.
