The ultimate workbench to test, debug, and demonstrate your extension features in real-time.
Remove disabled and readonly states
Unlock field characters boundaries
Convert hidden text inputs dynamically
When the password revealer runs, the extension shifts the type attribute of input fields from password to text.
Test global typeface modifications
This text box is designed to verify Google Fonts styling. When you apply fonts via the CodeSavvy popup, you will see this typography adapt instantly.
Toggles document.designMode state
Once Edit Mode is active (via the extension popup or the key combination Ctrl+Shift+Y), you can click directly on this paragraph and type/delete characters as if it were a word processor.
Select text, right-click, select AI enhancement
Right-click to swap casing or fix layouts
Interactive highlighter and layout utilities
Use the screenshot button in the extension popup to capture this canvas.
Blocks default context menus
Try right-clicking inside this box. A warning log and alert will trigger, and the context menu will be blocked.
How it works: The page listens to the contextmenu event and executes e.preventDefault(). Bypassing it overrides this capture phase.
Restricts highlighting and copying
This text is completely unselectable! It has user-select: none style applied and is covered by an invisible transparent shield div to block drags.
How it works: Clicking the Select Text button injects a global stylesheet overriding all user-select properties and removes unselectable elements/overlays.
Blocks clipboard operations
Highlight and copy this text: "CS-SECRET-PASSPHRASE". The site will intercept the copy event and block it.
How it works: The site blocks copy, cut, and paste events. CodeSavvy registers high-priority capturing listeners to allow them.
