Yes, start at the beginning of your test and hold down the left button of your mouse and drag it over the text you want to copy. This text will turn dark blue. Make sure you go to the end of the last sentence you want to copy.
Release the mouse button.
If you just want to print it from here (be sure not to remove the dark blue from the text you want to copy) then click on file, click on print, then make sure you highlight "selected text" from somewhere on the left, middle section of the print box.
Click on that option.
Hit Enter on your keyboard.
