Browser extensionfreeglobal

cmdOS is a browser extension that adds a keyboard-triggered command bar (Alt+S) to run searches, browser commands, and web shortcuts from one place instead of navigating menus and bookmarks by hand. It's local-first with no account required, aimed at power users who want to browse and act faster using the keyboard.
