How do you (efficiently) collect cropped screen shots of CAE/Abaqus for documentation ?

I want to use screen shots of CAE/Abaqus to create tutorials for specific simulations using CAE/Abaqus but it is very time consuming for me to collect the screen shots. I am using Prinscreeen, then in Paint, Paste, Crop, Save, then insert in my  document.  Does anyone know of a more efficient way of collecting cropped screen shots ?
