Microsoft is updating the Snipping Tool in Windows 11 with a new feature called Quick Markup, available in the Dev and Canary builds. This feature allows users to annotate screenshots before capturing them, streamlining the process. Users can activate Quick Markup via a button in the toolbar or the keyboard shortcut Ctrl + E. Other updates in Windows 11 include Paint's ability to save images as project files and an opacity slider for brushes, as well as Notepad's new AI features like "Summarize," "Write," and "Rewrite" for Copilot+ PCs.
