 ## Capturing one window on MacOS
-After pressing ++cmd+ctrl+shift+4++, press ++space++ and then left-click on the window you want to capture. This will automatically just take a screen shot of the active window which is indicated by the :material-camera: icon. As per the default, this also includes a drop shadow. You can also remove this shadow by pressing ++option++ after you pressed ++space++ but before left-clicking.
