Toggle Case

Toggle the letter case of selected text. If any lowercase letter is present, the selection becomes uppercase; if everything is already uppercase (or contains no lowercase letters), the selection becomes lowercase.

Usage

• Run the command Toggle Case (toggle-case.toggleCase).
• Default keybinding: Ctrl+Shift+U on Windows, Linux, and macOS.
• Remap the shortcut via File → Preferences → Keyboard Shortcuts and search for Toggle Case.
