Manipulate files:

1. C-x C-f Find a file (allows TAB completion)
2.  C-x C-s Save a copy of the current buffer to
     the corresponding file. If the buffer is not associated
     with a file, it'll prompt for a file name.
3. C-x s Save some buffers with the option of selectively
    saving them.

Manipulate buffers: 

1. C-x C-b List all buffers
   (then C-x 1 to kill the window showing the list)
2. C-x b Prompts for the buffer to go to (allows tab completion)
3. C-x k Prompts for the buffer name to kill
4. C-x C-q Toggle read-only mode

Manipulate windows:

1. C-x 0 Delete current window
2. C-x 1 Delete all but the current window
3. C-x 2 Split the window vertically
    (with a horizontal line in the middle)
4. C-x 3 Split the window horizontally
   (with a vertical line in the middle)
5. C-x o Move to the other window
6. C-M-v Scroll the other window

[emacs] Absolute basics — one step at a time: cursor movement

This is a continuation of my effort to get used to emacs editor. I just realized that there is no point in listing all the commands together at one post — simply because I missed a lot of useful ones the first time. So, let’s do it step-wise — one category at a time. Today, just the ‘cursor movement’: (Hit C-h t to get to the inbuilt tutorial)

Lines (vertically):

   
    1. C-n next line
    2. C-p previous line

Lines (Horizontally):

    3. C-a Move to the beginning of a line
    4. C-e Move to the end of a line

    5. C-f move forward one character
    6. C-b move backward one character

    7. M-f move forward one word
    8. M-b Move backward one word

Sentences: 

    5. M-a Move to the beginning of a sentence
    6. M-e Move to the end of a sentence

Paragraphs:

    7. M-{ Beginning of a paragraph
    8. M-} End of a paragraph

Pages: 

 
     9. C-x [ Beginning of the page
   10. C-x ] End of the page

Buffers:

   11. M-< Move to the beginning of the current buffer
   12. M-> Move to the end of the current buffer

N.B. “C-u <n>" or "M-<n>" is the command for numeric argument, i.e.

   1. C-u 7 *  Inserts "*" seven times
   2. M-8 C-f forwards the cursor 8 letters

Just add your signature in a file, say, ~/.signature and update the ~/.muttrc (or ~/.mutt/muttrc file, depending on where you put all your mutt aliases) by adding the following line:

set signature="~/.signature"
