🎯 I created this add-on because Facebook and Messenger, being half-baked non-functional websites, don't have keyboard shortcuts for text formatting.

• Please use this add-on on Facebook chats, Messenger conversations, and group posts. Facebook doesn't support text formatting for profile posts, page posts, comments, and replies.
• After (selected) text is formatted, text cursor is located at the back of the formatted text instead of last position due to Facebook/Messenger’s React + Lexical editor.
• Text wrapped with multiple format symbols is rendered properly on applications but not websites. Facebook just sucks 🤦.
