I'm using sml-mode (Stefan Monnier) with emacs. The compiler is smlnj, on a laptop. However, when invoking the SML compiler, that splits the emacs frame into two windows, each fits 12 lines. How can I have the SML program editing buffer in its own emacs frame, and the SML-Inferior-Mode buffer on a separate emacs frame? Thank you.
It was really straight!
First, invoke the SML compiler: C-c C-b
it asks for the default SML System: SMLNJ, MosML, etc.
type the name of the compiler to invoke, or press RETURN key to accept the default, if any.
Then, have the compiler window to display on its own frame, C-x 5 2
To kill (delete) the compiler window from within the SML program editing window, visit that window (either C-x o (letter o)) or by mouse. Then press C-x 0 (zero).

I am aware of this option:
Kill the *terminal* buffer with C-d
But I am still a newbie in emacs, what is the original method to do this? I tried C-x k but it doesn't like it, C-x C-c kills all my windows and buffers...
I assume you're using a buffer in term-mode (M-x term). term-mode is a bit different than most modes in that it has two submodes, char and line. In char mode it acts more like a terminal than emacs, as in a lot of normal keybinds are not available. Put it in line mode with C-c C-j to put it in line mode, then you can run most normal keybinds including C-x k. You can put it back into char mode with C-c C-k.
I use the multi-term package, which I think has better defaults than plain term-mode and as the name suggests makes it easy to have many terminal buffers.
When I'm running a terminal inside emacs (with M-x term) I can't seem to use commands that start with C-X, such as, say C-x o to switch panes or C-x C-c to exit. Instead it seems that the terminal itself is receiving these C-x signals. By contrast, C-c commands are received by emacs itself. How can I change this behavior?
term has two different input submodes. In the default (character) mode, C-x simply transmits a literal control x to the terminal. Many keybindings which are normally available in the C-x map are instead now in the C-c map, so you can switch to a different buffer in the other window with C-c 4 b. Or you can switch to line mode with C-c C-j (and back to character mode with C-c C-k).

I'm using emacs 23 (acquamacs) and have installed nrepl.el.
I've evaluated some Clojure code with
C-c C-p
(this key combo is to Evaluate the form preceding point and display the result in a popup buffer.)
Running it has produced a nice popup buffer for me to see the results.
How do I hide this popup buffer? (I don't want to kill it - just get my fullscreen back).
FYI Re this command - I've run this with
C-h k C-c C-p
and got
^C ^P runs the command nrepl-pprint-eval-last-expression, which is an interactive compiled Lisp function in `nrepl.el'.
It is bound to ^C ^P, <menu-bar> <nREPL> <Eval last expression in popup buffer>.
(nrepl-pprint-eval-last-expression)
Evaluate the expression preceding point and pprint its value in a popup buffer.
You haven't provided enough information for anyone to test (that's not a standard global binding), and you haven't even indicated whether the new window is selected; but there's a generic solution which will work regardless.
Add (winner-mode 1) to your init file, and then you can always use C-c<left> to undo the most recent window configuration change (or changes plural, if you repeat the command).
Either that or just press q. I just tried it out with the help buffer and it dismisses the window but not the buffer. However, popup buffers in the style of ac-nrepl does for its autocompletion are meant to simply be dismissed
Always, when asking Emacs questions, say what the key sequence does. C-c C-p does nothing here. TO find out what it does press C-h k C-c C-p and report back. In this case we're invoking 'describe-key and then telling it to describe what C-c C-p does.
I recently installed cygwin and emacs, and when I try to exit the program (by pressing C-x C-c) the minibuffer reads "C-x C-g is undefined". When I type C-c the minibuffer reads "Quit" just like if I had typed C-g. To the best of my knowledge, it's just reading the c key as a g in the minibuffer. However, if I type c into a scratch buffer it correctly displays c. Or if I type M-x c, it correctly reads as c in the minibuffer.
Is this a common problem? How do I fix this?
Thanks so much for any help! It's driving me crazy. Right now, I have to exit out of Cygwin when I want to quit emacs because C-x C-c won't close the program!
This is a problem with the default Cygwin console, but it doesn't happen with other Cygwin terminals such as mintty, rxvt, or xterm, so you might want to try one of those. Also, I believe the issue with the console is fixed in recent Cygwin snapshots.
I find the narrow-to-region command useful, however it applies to the buffer and not to the current window.
I'd like to have one window display a narrowed version of the buffer, while the buffer is displayed widened if it occurs in any other window.
Is this possible?
Try M-x clone-indirect-buffer or C-x 4 c. For details,
see Indirect Buffers.
