How do you restrict screenshot only to certain portion?

To restrict screenshots to a specific portion of the screen, you can use built-in operating system tools or third-party software that allows for selective screenshotting. For example, on Windows, the Snipping Tool or Snip & Sketch lets you select a specific area to capture. On macOS, you can use the shortcut Command + Shift + 4 to draw a selection box around the desired area. Additionally, some applications may have their own screenshot features that provide options for limiting captures to designated sections.
