>>> If you have, like me, a textbook that is 800 pages with thousands of figures, breaking up the manuscript into sections or chapters and having the ability to typeset a small subset of the manuscript is essential. On a top-of-the-line 2012 MacBook Pro with an SSD, it takes 64 seconds to typeset the entire thing. It takes a couple of seconds to typeset an individual section from a chapter.

Sometimes, you are trying to fine tune a small tyepsetting issue and need dozens of trials with very small adjustments, and in this situation being able to typeset only a chapter or a section is really helpful. Also, when building complicated presentations with beamer, with overlays and other nice features which demand retypesetting the same frame again and again, beamer's ability to typeset only a single, or a few frames, is very helpful.

Rather than prescribing the particular frame to typeset from the beamer document preamble, select the frame to edit, copy it to the Experiment window and press its Typeset button until you get a satisfactory result, then copy back to the main document. (The Experiment window uses the same preamble as the main document.) This is of course useful not just in beamer---it's a big help when typesetting a messy group of equations within a large document.

What an incredible feature! I have not tried it extensively but the potential is amazing. I haven’t experimented with the ``then copy back to the main document’’ yet but will try that on a small document. It should be a Godsend when adjusting pics by Tikz.

The TeX, LaTeX, TeXShop combination is beyond compare, and people who support it cannot be given adequate, sufficient, enough praise.

With a 400 page document, in DRAFT mode, on my 2010 iMac, a typeset which includes all chapters is too slow for me, hence I regularly use the \includeonly command, which I learned from George’s book,  :-) and work on a single chapter most of the time.

TeXShop 3.49 running under Mavericks 10.9.5
