Script Menu is a Chrome add-on developed by 安東邦泰. It allows users to execute scripts or bookmarklets directly from the right-click context menu. This handy tool eliminates the need for manual navigation to execute scripts, making it a time-saving feature for programmers.

With Script Menu, users can quickly execute scripts without the need for any GM_* functions. The latest version, v4.6, includes bug fixes to ensure smooth functionality. However, it's important to note that this add-on is not recommended for beginners, as it may be too complex for those with limited programming knowledge.

Overall, Script Menu is a useful tool for experienced programmers who frequently execute scripts. It streamlines the process and saves time by providing a convenient way to execute scripts directly from the right-click context menu in Chrome.
