Windows shortcuts

GNOME keyboard shortcuts are a bit arcane, unknown.
Windows ones are more like a standard due to 90%+ market share.

I propose changing default shortcuts as below:

  • :ballot_box_with_check: Super+E - launch Nautilus
  • :ballot_box_with_check: Super+D - hide/show all windows
  • Ctrl+Shift+Esc - launch System Monitor
  • Shift+Super+S - "Copy a screenshot of an area to clipboard"
  • more i might've omitted
