AlternaText is a smart text transformation tool that converts any selected text into alternating case format. The extension intelligently handles Unicode characters using modern browser APIs and skips non-alphabetic characters (spaces, punctuation, numbers) while maintaining the alternating pattern for letters only.
Key Features:

Smart alternating case conversion - Transforms text like "Hello World!" into "hElLo WoRlD!"
Unicode support - Properly handles international characters and emojis using Intl.Segmenter
Multiple activation methods - Browser action button, right-click context menu, or keyboard shortcut (Ctrl+Shift+U)
Works everywhere - Supports both text inputs/textareas and regular text selections on web pages
Non-intrusive - Only processes selected text, leaving everything else untouched
Visual feedback - Subtle animation when no text is selected

Technical Highlights:

Uses grapheme clustering for proper Unicode handling
Maintains cursor position after transformation
Triggers appropriate events for form compatibility
Lightweight with no external dependencies

Perfect for adding a playful touch to your text or creating that distinctive alternating case style popular in memes and casual communication.
