Microsoft's **PowerToys** is a free, open-source software suite that adds extra tools and features to the Windows operating system. One of its features is the **Shortcut Guide**, which helps users discover keyboard shortcuts for various applications. The guide appears as a vertical window that overlays the current application, showing available shortcuts. It supports popular programs like Microsoft Office, Discord, Firefox, Photoshop, and Slack, among others. To use the **Shortcut Guide**, users first need to download and install **PowerToys** from Microsoft’s website. Once installed, they can access the feature by opening the application and navigating to the "System Tools" section on the left side of the interface. From there, they should click on **Shortcut Guide**. If the feature isn't already enabled, users can activate it by checking the corresponding box. Additional settings allow users to customize the activation shortcut, adjust the window's appearance, and choose whether the guide appears on the left or right side of the screen. The default shortcut to open the **Shortcut Guide** is the Windows key, which is also used to display the numbers of open applications in the taskbar. However, users can change this shortcut if needed. To close the **Shortcut Guide**, they can press the Escape key, click outside the window, or use the close button in the top-right corner of the window. The feature also includes a search function, making it easier to find specific shortcuts. Additionally, users can click buttons to view keyboard shortcuts for other detected applications, including the Windows operating system itself. The **Shortcut Guide** is designed to improve efficiency by helping users navigate software more quickly through keyboard commands. It is particularly useful for power users and those who prefer keyboard shortcuts over mouse interactions. As part of the **PowerToys** suite, the feature is regularly updated to support new applications and improve usability.
