Emacs

These Emacs tips might be useful to somebody out there. And at the very least it will provide me with a place to look up things that I have already searched for before. Now that I look at them, they seem rather rudimentary but far be it from me to keep something that I found useful from others.

• (I’ve been trying to figure this one out for awhile.) To search for a string from one buffer in another buffer:
  1. C-w (or M-w) the search string
  2. move to the buffer to search in
  3. C-s
  4. M-y
• Synchronized scrolling: M-x scroll-all-mode
  • Scroll other window:
    • M-C-v scrolls down
    • M-C-V scrolls up
• Repeat a command numerous times: M-(number) (command) where you fill in (number) with a number and (command) with the command that you want to repeat. To use a number that is not a single digit you hold M while pressing the first number and then release M while pressing the rest of the numbers. An example: to kill 10 lines you would do: M-1 0 C-k.

Notes:
M is the Meta key (usually Alt or Esc depending on your operating system/settings)
C is the Control key

Emacs can be great if you know how to use it.
