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 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.
I'm trying to learn Emacs, and I've installed MELPA as a package manager. The only problem is that the only way I know how to exit MELPA is by quitting Emacs entirely. I'm sure there's a better way to do this. What is it?
Killing buffers with C-x k RET is generally good advice, but it is much easier to quit the package-list-packages screen by simply pressing q.
This also works to exit dired buffers, magit, and many other types of buffers that aren't text-oriented.
C-x C-f open file
C-x C-b open buffer list
C-x b open buffer
M-x execute command
C - ctrl and M - alt

Sorry if these are obvious answers but I've googled around and can't seem to find what I'm looking for.
When I have multiple files open in split screen mode using C-x C-3 how do I close JUST the window I'm currently in and no other?
I'm using Ruby and it doesn't seem to auto indent my def end correctly.. is there a Ruby plugin that will fix this?
Is there a command to go to a specific line?
How do I interpret ruby from within emacs?
1. When I have multiple files open in split screen mode using C-x C-3 how do I close JUST the window I'm currently in and no other?
To close current view C-x 0. (Btw, I think you're referring to C-x 3.)
2. I'm using Ruby and it doesn't seem to auto indent my def end correctly.. is there a Ruby plugin that will fix this?
Have a look at
ruby-mode for emacs
RubyMode
3. Is there a command to go to a specific line?
Sure, M-g g (or M-x goto-line)
4. How do I interpret ruby from within emacs?
Don't know. You could try rubydebug.
You can also see C-h b which will give you key binding for the current-buffer to give you a lot of additional things that you might need. Once you install any Ruby Mode, you can also use C-h m to see key binding for that specific modes in your current buffer, including ruby mode.
for Q3) in addition you might want to know
C-h w COMMAND
will always show you the key binding for a funcion
C-h w goto-line RET
goto-line is on M-g g, M-g M-g, <menu-bar> <edit> <goto> <go-to-line>
for Q4) you could start a shell in a buffer, either M-x eshell or M-x shell and the simply run your script there.
Using the eshell configuration in [1] you can easily switch between the shell and your script source (pressing C-z).

I load GNU emacs in it's own window by typing emacs in the terminal.
I like to use the keybindings from pc-selection-mode, which allows you to highlight characters using shift-right or shift-left, or entire lines by pressing shift-up or shift-down.
The problem is that when I run emacs in the terminal by typing emacs -nw, the latter 2 keybindings don't work. I can highlight characters using shift-left and shift-right, but pressing shift-up and shift-down doesn't do anything. The cursor stays where it is.
How do I fix this problem? Why is it even occurring? I'm using GNU Emacs 23.1.1, and I've confirmed that the same version is being used both when emacs is in it's own window and when emacs is running inside the terminal.
Thanks for any help
A lot of times the bindings just aren't listed, or are mapped wrong. You can try M-x show-lossage (or C-h l) to see if the escape sequences reach emacs or not. If they do, you might want to try xterm-extras -- it's always worked even as I migrate between different versions of linux and solaris, and as I ssh between them (which is often a source of problems).
I am unable to yank text into a terminal running in Emacs.
This is my procedure:
I killed the string "date" from one buffer and yanked it into the terminal in another buffer and hit return.
The terminal behaves as if I typed nothing. It just returns the prompt back.
I am using OS X 10.5.8 and Emacs 23.1. I have tried this procedure on Aquamacs, Carbon Emacs, and the release from http://emacsformacosx.com/. They all show this weird behaviour even in their default configurations with my .emacs file empty. What could possibly be causing this?
By "in a terminal" I assume you mean you're running Emacs's built-in terminal emulator. Ordinarily, the terminal emulator transmits most keys exactly as typed to the shell process. Type C-c C-j in the terminal buffer to put it into a state where ordinary Emacs key bindings are available. You'll see the mode line change from (Term: char run) to (Term: line run).
Addendum:
Yanking text without leaving char mode is a little tricky; the relevant function, however, is term-paste (not yank, which merely inserts the text into the terminal buffer without sending it to the inferior process). term-paste will immediately send the most recent kill to the inferior process, but doesn't provide the fancy yank functionality you're probably used to (like M-y to cycle through prior kills). You could run term-paste as an extended command: C-c M-x term-paste RET.
Probably the easiest solution is just to temporarily go into line mode (C-c C-j) when you have something to paste, and then immediately go back into char mode (C-c C-k). Or even easier, just stay in line mode all the time. I often do this when I have a terminal logged into an Oracle SQL*Plus session. I rarely notice the difference, but I get all sorts of convenient Emacs functionality, like being able to type M-p to cycle through a long, previously-typed SQL statement.
I would have assumed that you could always start off in line mode like this:
(add-hook 'term-mode-hook 'term-line-mode)
...but it doesn't work for me. Don't know why.
In the buffer with the terminal running, put the terminal into line mode with C-c C-j. To paste in your text, now press S-Insert (that's Shift-Insert). If you need the terminal to go back to char mode afterwards, it's C-c C-k.
When all else fails I just highlight the text and click Edit->Copy then right click in the other emacs buffer and click paste.
