Region capture

Region capture is the feature you will use most: select any rectangle on the screen, then annotate, copy, or save the image.

How to start

Press the capture shortcut (default Alt + Q), left-click the tray icon, or choose Capture from the right-click menu.
The screen enters selection mode. Drag over the area you want.
Release the mouse to open the preview and annotation view.

Tip: nudge the edges while selecting so the image contains only what you need. For a fixed region or a delay, press Alt + W to open custom capture.

Common actions in the preview

Copy: put the image on the clipboard so you can paste it immediately (Ctrl + C does the same in the session)
Save: export a local image file, such as PNG
Annotate: add arrows, shapes, text, mosaic, and more (see the annotation docs)
Record: start recording from the selection toolbar (see Screen recording)
Cancel: Esc drops this capture

Tips

For a whole window, hug the window edges so the desktop background stays out.
Cover account numbers, phone numbers, and other sensitive details with mosaic before you share.
If you want the original image with no marks, copy as soon as the selection is done.
