Complete Keyboard Shortcuts & Screenshot Guide
Master 100+ essential hotkeys, screenshot commands, AI prompt tricks, and gestures across all operating systems and applications.
Start with a task, then learn the keys
Choose the operating system you are using before copying a shortcut. A plus sign means hold the keys together; release them after the command runs. Windows uses Ctrl and the Windows key for many commands, while Mac and iPad often use Command. An app can assign a different action to the same combination.
For a practical starting point, follow the Windows screenshot workflow, try the browser research exercise, or learn how iPad keyboard screenshots differ from Mac. Each guide includes context and troubleshooting so you can understand the result.
Try one command in a sample document before using it on important work. If it fails, check keyboard focus, your app version, and custom key mappings. Read about our content and corrections to report a specific error.
