A VS Code extension that toggles selected text between UPPERCASE and lowercase.
Features
Press Shift+Alt+U (or run Toggle Case from the Command Palette) to switch between cases. Select text first, or just put the cursor in a word and the word is toggled and selected.
All-uppercase text → lowercase
Everything else (lowercase or mixed case) → UPPERCASE
Works with multiple cursors / multiple selections; one undo reverts them all
With no selection, toggles the word under the cursor (using the language's own definition of a word)
Works in VS Code for the Web (vscode.dev, github.dev) as well as the desktop editor
Usage
Select the text you want to change, or place the cursor in a word
Press Shift+Alt+U — or open the Command Palette and run Toggle Case
