I do it the hard way: Highlight the area to quote, then hit CNTL C, move the cursor to where you want the quote and hit CNTL V. Don't forget to put it in quote marks.
That's the way I do it, too. I'm not very sophisticated and I'm still getting used to things around here.
I will say in regards to writing in general, two spaces between sentences is correct. Also, if you read it aloud, you will generally know when you need a comma or need to start another sentence. If you're out of breath, then you definitely need to start another sentence and or paragraph--unless you're a beat poet like Ginsberg.
Paragraphs are very helpful to organize thoughts and give the reader a moment to think about what you've just said. Also, for someone like me, it takes a bit to absorb some of this mind blowing technological information that is put out there. Yes, I can do the math, but I need a moment here and there so my head doesn't explode.
Sorry that I went off topic. I'm very interested in the actual information regarding ovens, construction, indoors or outdoors, etc. But gee, sometimes you guys make my head spin. Seriously, I appreciate all of the input; if I end up building my own WFO, this site is priceless as far as what I need to take into consideration. Now about that Black Stone...
