# Guidelines for user interface text in SerenityOS

## Capitalization

SerenityOS employs two capitalization styles:

- Book title capitalization
- Sentence-style capitalization

### Book title capitalization

In this style, we capitalize the first letter of the first and last word,
as well as all words in between, *except* articles (a, an, the);
the seven coordinating conjunctions (for, and, nor, but, or, yet, so);
and prepositions with up to four letters (at, by, for, with, into, ...)

#### Examples:
- Create New Layer
- Copy URL
- Move to Front
- Save and Exit
- Sort by Name

#### Used for:

- Button text
- Icon labels
- Menu names
- Menu items
- Tab titles
- Window titles
- Tooltips

### Sentence-style capitalization

This style follows basic English sentence capitalization.
We capitalize the first letter of the first word, along with the first letter
of proper names, weekdays, etc.

#### Examples:
- An error occurred
- Use system defaults
- Copy the selected text
- Enable Linux compatibility hacks

#### Used for:

- Check box labels
- Group box labels
- List items
- Messages (as in message boxes)
- Radio button labels
- Status bar text
- Text box labels
