4 Smart Shortcuts is a free Chrome add-on developed by rawbytz that allows users to define custom keyboard shortcuts for their favorite websites. With this handy tool, users can easily navigate to their preferred sites with just a few keystrokes.

One of the standout features of 4 Smart Shortcuts is its ability to match keyboard shortcuts to existing tabs. If a matching tab is found, the add-on will navigate to that tab instead of creating a new one. This ensures that users don't end up with multiple tabs for the same website, making it a great option for those who like to keep their browser clutter-free.

The add-on also supports "chrome://" system shortcuts, such as "chrome://extensions" and "chrome://apps". This means that users can create keyboard shortcuts for accessing various Chrome settings and features.
