Hiding green work area border temporarily
Environment
Not environment-specific
If you need to take a cleaner screenshot from a model view, and you don't want to include the green work area border into the screenshot, you can easily hide it with this shortcut:
Ctrl + Shift + right click Redraw View (from pop-up menu)
Image
Work area border is hidden only temporarily. When you redraw the view again, you get the work area border back.
