Editing blocks of text
Note: the Vim commands marked with (V) work in visual mode, when you've selected some text. The other commands work in the command mode, when you haven't selected any text.
Vim command 	Action
~ 	Change the case of characters. This works both in visual and command mode.
        In visual mode, change the case of highlighted characters. 
        In command mode, change the case of the character uder cursor.
> (V) 	Shift right (indent).
< (V) 	Shift left (de-indent).
c (V) 	Change the highlighted text.
y (V) 	Yank the highlighted text. In Windows terms, "copy the selected text to clipboard."
yy or :y or Y     Yank the current line. You don't need to highlight it first.
d (V) 	Delete the highlighted text. In Windows terms, "cut the selected text to clipboard."
x     Delete characters under the cursor.
X     Delete characters before the cursor.
dd or :d 	Delete the current line. Again, you don't need to highlight it first. Deleting text
p 	Put the text you yanked or deleted. In Windows terms, "paste the contents of the clipboard". 
        Put characters after the cursor. Put lines below the current line.
P 	Put characters before the cursor. Put lines above the current line.
u  	Undo the last action.
U 	Undo all the latest changes that were made to the current line.
Ctrl + r 	Redo.
v  	Start highlighting characters. Use the normal movement keys and commands 
        to select text for highlighting.
V 	Start highlighting lines.


:%! nl -ba   # Line Numbers

Finding Files
---------------------
:pwd  # print working directory
:cd   # change directory
:find # file name (within path)


Search
---------------------
* /i – Search for a pattern which will you take you to the next occurrence of it.
* ?i – Search for a pattern which will you take you to the previous occurrence of it.
* * - Go to the next occurrence of the current word under the cursor.
* # - Go to the previous occurrence of the current word under the cursor.

re-apply - The . command repeats the last change. A change, in this context, is inserting, deleting or replacing text. Being able to repeat this is a very powerful mechanism. If you organise your editing around it, many changes will become a matter of hitting just that . key. Watch out for making other changes in between, because it will replace the change that you were repeating. Instead you might want to mark the location with the m command, continue your repeated change and come back there later.

registers - When you are typing a phrase or sentence multiple times, there is an even quicker approach. Vim has a mechanism to record a macro. You type qa to start recording into register 'a'. Then you type your commands as usual and finally hit q again to stop recording. When you want to repeat the recorded commands you type @a. There are 26 registers available for this.

:tabnew [filename] # and Vim will load the file in the new tab (or defaults to empty buffer)
:tabs # displays all tabs
:tabn and :tabp switch between tabs, or you can use gt while you're in normal mode.

If you have a lot of tabs open, you can use :tabfirst, or just :tabfir, to jump to the first tab, and :tablast to jump to the last tab that's open.

if you don't like the existing shortcuts for the tab commands, you can add your own. For instance, if you want to make it easy to open a new tab, you might insert this into your .vimrc:

- Rearranging tabs
If you're really meticulous and want to position tabs just so in Vim, you can move the tabs to a specific spot in the tab order using :tabm n , where n is the position number that you want to use. If you don't give the :tabm command an argument, then the current tab will be moved to the last spot.

Vim starts tab numbering from 0, so if you have six tabs open, you'll have tab 0 through tab 5. So, if you're in the first tab and want to move it to the fourth position, you'd run :tab 3.

map <leader>tn :tabnew %<cr>
map <leader>tc :tabclose<cr>
map <leader>tm :tabmove 


:split [file]  # Splits the window horizontally.
:vsplit [file] # Splits the window vertically.
<Ctrl>-w       # (mnemonic: control window) To move between windows you use <Ctrl>-w (mnemonic: control window). 
               # To move in a specific direction, add the relevant movement key. So, to move upwards: <Ctrl>-w+k.
               # To close the active window use :q, just as you would to close a window normally.
<Ctrl>-w [HJKL] # to actually move buffer (i.e. K will move current buffer to top. * notice caps*)
:only          # if split buffers, close all buffers except current one.
You can reduce/enlarge the size of the current window with <Ctrl>-w+- and <Ctrl>-w++, respectively. To specify the size of a window when you open it, prefix the :split command with the desired height/width in lines. For example, to show README in a window of 5 lines high: :5 :split README.

When splitting a window you can prepend a modifier command to tell where the
window is to appear:
:leftabove {cmd} left or above the current window
:aboveleft {cmd} idem
:rightbelow {cmd} right or below the current window
:belowright {cmd} idem
:topleft {cmd} at the top or left of the Vim window
:botright {cmd} at the bottom or right of the Vim window


CTRL-W x					
CTRL-W CTRL-X	Without count: Exchange current window with next one.  If there
		is no next window, exchange with previous window.
		With count: Exchange current window with Nth window (first
		window is 1).  The cursor is put in the other window.


Replace
Vim command 	Action
:rs/foo/bar/a 	Substitute foo with bar. r determines the range and a determines the arguments.
The range (r) can be
nothing 	Work on current line only.
number 	Work on the line whose number you give.
% 	The whole file.
Arguments (a) can be
g 	Replace all occurrences in the line. Without this, Vim replaces only the first occurrences in each line.
i 	Ignore case for the search pattern.
I 	Don't ignore case.
c 	Confirm each substitution. You can type y to substitute this match, n to skip this match, a to substitute this and all the remaining matches ("Yes to all"), and q to quit substitution.
Examples
:452s/foo/bar/ 	Replace the first occurrence of the word foo with bar on line number 452.
:s/foo/bar/g 	Replace every occurrence of the word foo with bar on current line.
:%s/foo/bar/g 	Replace every occurrence of the word foo with bar in the whole file.
:%s/foo/bar/gi 	The same as above, but ignore the case of the pattern you want to substitute. This replaces foo, FOO, Foo, and so on.
:%s/foo/bar/gc 	Confirm every substitution.
:%s/foo/bar/c 	For each line on the file, replace the first occurrence of foo with bar and confirm every substitution.

# Sessions
--------------------------
:mksession my_session.vim # creates session with current layout info 
:source my_session.vim    # restore session from file (or :~>vim -S my_session.vim)


BUFFERS
--------------------
:bn[ext]           # Next buffer
:bp[revious]       # Previous Buffer
