Text case types
Use sentence and title styles for prose, capitalization for headings, and snake_case, kebab-case, dot.case or path/case for developer and filename conventions. Toggle Case inverts letters, while Alternating Case creates alternating capitalization.
Title Case vs Capitalize Each Word
Title Case keeps many short connecting words lowercase except at the beginning or end. Capitalize Each Word gives every detected word an initial capital, which can be useful for names and labels.
