Go to the beginning of the region and hit C-space. Go to the end, and type C-w to cut or M-w to copy. Go to the destination, and type C-y to paste.

11. When I try to do C-x C-s or C-x C-c nothing happens. Why?

If you are telnetting from a Macintosh, the problem is that the telnet program is intercepting the keystrokes. Disable that (how to do this varies by program). If you are not telnetting from a Macintosh, zephyr rsi-help.

12. I can't stand that my LaTeX files are color coded. How do I get rid of this?

Edit your ~/.emacs file (emacs ~/.emacs). Remove (or comment out, by placing a ;; at the beginning of each line) everything beneath "turn on font-lock-mode." You won't ever see the color coding again, unless you turn it back on.
