Simple way to take a screenshot of the display

[remino]

I wish there was a simple way to just hit a keyboard shortcut or click a toolbar icon to just take a simple screenshot of the VM’s display and the original resolution; with no distortion, filter, or scaling.

I know I can take screenshots using tools in macOS, but then that means I still get the window’s chrome surrounding the display, and the corners are rounded off. I don’t want that. I just want the original display as it is.
