    k
  h   l         basic motion
    j

w               next start of word
W               next start of whitespace-delimited word
e               next end of word
E               next end of whitespace-delimited word
b               previous start of word

0               start of line
$               end of line
gg              go to first line in file
G               go to end of file
gk		move down one displayed line
gj		move up one displayed line

# Insertion
#   To exit from insert mode use Esc or Ctrl-C
#   Enter insertion mode and:

a               append after the cursor
A               append at the end of the line
i               insert before the cursor
I               insert at the beginning of the line
o               create a new line under the cursor
O               create a new line above the cursor
R               enter insert mode but replace instead of inserting chars

# Editing

u               undo
yy              yank (copy) a line
y{motion}       yank text that {motion} moves over
p               paste after cursor
P               paste before cursor
<Del> or x      delete a character
dd              delete a line
d{motion}       delete text that {motion} moves over

# Search and replace with the `:substitute` (aka `:s`) command

:s/foo/bar/	replace the first match of 'foo' with 'bar' on the current line only
:s/foo/bar/g	replace all matches (`g` flag) of 'foo' with 'bar' on the current line only
:%s/foo/bar/g	replace all matches of 'foo' with 'bar' in the entire file (`:%s`)
:%s/foo/bar/gc	ask to manually confirm (`c` flag) each replacement

# Preceding a motion or edition with a number repeats it 'n' times
# Examples:
50k         moves 50 lines up
2dw         deletes 2 words
5yy         copies 5 lines
42G         go to line 42

:e filename      - edit another file
:split filename  - split window and load another file
ctrl-w up arrow  - move cursor up a window
ctrl-w ctrl-w    - move cursor to another window (cycle)
ctrl-w_          - maximize current window
ctrl-w=          - make all equal size
10 ctrl-w+       - increase window size by 10 lines
:vsplit file     - vertical split
:sview file      - same as split, but readonly
:hide            - close current window
:only            - keep only this window open

:bf              - goes to first buffer
:bl              - goes to last buffer
:b 2             - open buffer #2 in this window
:new             - open a new buffer
:vnew            - open a new vertical buffer
:bd 2            - deletes buffer 2
:wall            - writes all buffers

# Pointers back
ctrl-o

# Pointers forward

# Super search
ctrl-p

# To sort  a visual range on column 1 as a number:
:'<,'>!sort -gk 1 -t ,

# Map (in normal mode) the F2 key to a bash call `uuidgen`, then trim the `\n`
# from the result, and put that in the expression register `"=`, then put that
# before the cursor:
nmap <F2> "= system("uuidgen")[:-2]<C-M>P

# Delete every line that has a FOO in it. See `:help global`.
# The _ in the d _ command ensures registers and clipboards are not changed.

 tldr:vim 
# vim
# Vim (Vi IMproved), a command-line text editor, provides several modes for different kinds of text manipulation.
# Pressing `i` in normal mode enters insert mode. Pressing `<Esc>` goes back to normal mode, which enables the use of Vim commands.
# See also `vimdiff`, `vimtutor`, `nvim`.
# More information: <https://www.vim.org>.

# Open a file:
vim path/to/file

# Open a file at a specified line number:
vim +line_number path/to/file

# View Vim's help manual:
:help<Enter>

# Save and quit the current buffer:
:wq<Enter>

# Enter normal mode and undo the last operation:
<ESC>u

# Search for a pattern in the file (press `n`/`N` to go to next/previous match):
/search_pattern<Enter>

# Perform a regular expression substitution in the whole file:
:%s/regular_expression/replacement/g<Enter>

# Display the line numbers:
:set nu<Enter>
