:[range]d[elete] {count}	Delete {count} lines, starting with [range]

---

Changing (or Replacing) Text

r{char}	replace the character under the cursor with {char}.
R	Enter Insert mode, replacing characters rather than inserting
~	Switch case of the character under the cursor and move the cursor to the right. If a [count] is given, do that many characters.

Substituting

:[range]s[ubstitute]/{pattern}/{string}/[c][e][g][p][r][i][I] [count]	For each line in [range] replace a match of {pattern} with {string}.
:[range]s[ubstitute] [c][e][g][r][i][I] [count] :[range]&[c][e][g][r][i][I] [count]	Repeat last :substitute with same search pattern and substitute string, but without the same flags. You may add extra flags

The arguments that you can use for the substitute commands:
[c]  Confirm each substitution.  Vim positions the cursor on the matching
 string.  You can type:
     'y'      to substitute this match
     'n'      to skip this match
        to skip this match
     'a'      to substitute this and all remaining matches {not in Vi}
     'q'      to quit substituting {not in Vi}
     CTRL-E  to scroll the screen up {not in Vi}
     CTRL-Y  to scroll the screen down {not in Vi}.
[e]     When the search pattern fails, do not issue an error message and, in
 particular, continue in maps as if no error occurred. 
[g]  Replace all occurrences in the line.  Without this argument,
 replacement occurs only for the first occurrence in each line.
[i]  Ignore case for the pattern. 
[I]  Don't ignore case for the pattern. 
[p]  Print the line containing the last substitute.

A word consists of a sequence of letters, digits and underscores, or a sequence of other non-blank characters, separated with white space (spaces, tabs, ). This can be changed with the 'iskeyword' option.

A WORD consists of a sequence of non-blank characters, separated with white space. An empty line is also considered to be a word and a WORD.

][	[count] sections forward or to the next '}' in the first column
[[	[count] sections backward or to the previous '{' in the first column
[]	[count] sections backward or to the previous '}' in the first column

Marks

m{a-zA-Z}	Set mark {a-zA-Z} at cursor position (does not move the cursor, this is not a motion command).
m' or m`	Set the previous context mark. This can be jumped to with the "''" or "``" command (does not move the cursor, this is not a motion command).
:[range]ma[rk] {a-zA-Z}	Set mark {a-zA-Z} at last line number in [range], column 0. Default is cursor line.
:[range]k{a-zA-Z}	Same as :mark, but the space before the mark name can be omitted.

Selecting Text (Visual Mode)

To select text, enter visual mode with one of the commands below, and use motion commands to highlight the text you are interested in. Then, use some command on the text.

The operators that can be used are:
 ~  switch case
 d  delete
 c  change
 y  yank
 >  shift right
 <  shift left
 !  filter through external command
 =  filter through 'equalprg' option command
 gq  format lines to 'textwidth' length

v	start Visual mode per character.
V	start Visual mode linewise.
	exit Visual mode without making any changes

---

How to Suspend

CTRL-Z	Suspend Vim, like ":stop". Works in Normal and in Visual mode. In Insert and Command-line mode, the CTRL-Z is inserted as a normal character.
:sus[pend][!] or :st[op][!]	Suspend Vim. If the '!' is not given and 'autowrite' is set, every buffer with changes and a file name is written out. If the '!' is given or 'autowrite' is not set, changed buffers are not written, don't forget to bring Vim back to the foreground later!

# colourshell.sh

# Please copy these into a file named .colourshell.sh at home. Then plus ". .colourshell.sh"
# to the the .bashrc.

# In an interactive Bash shell, cycles through a sequence of colours,
# one per command, so that you can more easily see where one finishes
# and the next starts.

# As far as I'm aware this won't work in any shells other than bash
# because it uses bash-specific features.

# To try it out, source this file into an interactive shell:
# source /path/to/colourshell.sh

# For permanent use this file should be sourced from your bash startup
# script(s).
#
# Bash may execute various different startup scripts; see the
# INVOCATION section of the bash man page for details.  To have this
# script called for both login shells (e.g. virtual consoles) and
# non-login shells (e.g. xterms) you need to call it from both
# .bash_profile and .bashrc.  .bashrc may also be called for
# non-interactive shells; to avoid running this in that case you can
# enclose the source command in an if block that tests for
# interactivity by checking for PS1:
#
# if [ "$PS1" ]
# then
#   source /path/to/colourshell.sh
# fi

# Source this from somewhere near the end of those files.  In
# particular, source it from after any code that sets the prompt
# variables (PS1 etc.) since this code adds its stuff to the existing
# PS1 setting.

# If your startup scripts don't set PS1 to PS4, things could get
# interesting if you start one shell inside another: this code will be
# called twice!  It should still work, but ideally this script would
# scrub any existing colour-setting codes from the prompts before
# adding its own.

# This code generates colour-changing escape sequences using the tput
# program.  This is a simple utility that uses the termcap database to
# look up escape sequences for the current terminal.  It seems to be
# included in the major Linux distributions.  For details, see "man
# tput" and "man 5 terminfo".  In particular see the "Color Handling"
# section of "man 5 terminfo".

# Most terminals with colour support have 8 colours.  An exception is
# rxvt-unicode (and other rxvts?) which claims to have 88.  This script
# doesn't know what to do with any other cases, so gives up immediately
# without error.

ncolours=`tput colors`
case $ncolours in
8) ;;
88) ;;
*) return 0 ;;
esac

# The following are the standard colour codes; see "man 5 terminfo".

setaf_black=`tput setaf 0`
setaf_blue=`tput setaf 1`
setaf_green=`tput setaf 2`
setaf_cyan=`tput setaf 3`
setaf_red=`tput setaf 4`
setaf_magenta=`tput setaf 5`
setaf_yellow=`tput setaf 6`
setaf_white=`tput setaf 7`

# For 88-colour rxvt-unicode these 8 colours are near-enough right.
# Try something like this to see the available colours:
#
# i=0
# while true
# do
#   tput setaf $i
#   echo "$i: Hello World"
#   i=$(($i+1))
# done

# Define the colours to use.
# Set prompt_colour to the escape sequence for the colour to use for
# the prompt, and cmd_colours (an array) to the escape sequences for
# the colours to use for the commands, in turn.

declare -a cmd_colours

# A complicating factor is that we don't know whether this terminal
# has a white / light-coloured background or a black / dark-coloured
# background.  This should influence our choice of colours.

# Here is a heuristic: virtual consoles have TERM=linux and are
# white-on-black, while X terminals and similar have TERM=xterm and
# are black-on-white.

case $TERM in
linux)   background=dark ;;
*xterm*) background=light ;;
*)       background=light ;;
esac

# Choose colours, based on the guessed background colour:

case $background in
dark)  prompt_colour=$setaf_white
      cmd_colours=($setaf_cyan $setaf_magenta $setaf_yellow) ;;
light) prompt_colour=$setaf_black
      cmd_colours=($setaf_blue $setaf_green $setaf_red) ;;
esac

# This variable tracks which command colour is currently in use:

declare -i cmd_colour_index=-1

# This function increments cmd_colour_index modulo the number of
# command colours:

function next_colour() {
 cmd_colour_index=$(( ($cmd_colour_index+1) % (${#cmd_colours[*]}) ))
}

# PROMPT_COMMAND is a bash builtin variable that names a command to
# run before each prompt.  (This will override any existing use of
# this variable; how can multiple commands be chained together?)

PROMPT_COMMAND=next_colour

# This function returns the escape sequence for the current command
# colour, from the array defined above:

function cmd_colour() {
 echo ${cmd_colours[$cmd_colour_index]}
}

# Define the prompt variables.  For each one we encapsulate the
# current setting between a prefix and a suffix; the prefix sets the
# colour for the prompt and the suffix sets the colour for the
# command.

# \[ ... \] are used around non-printing characters and are needed so
# that Bash correctly calculates the screen position.  Functions can
# be called using `...`, as long as the promptvars option is enabled:

shopt -s promptvars

prompt_prefix="\\[${prompt_colour}\\]"
prompt_suffix='\[`cmd_colour`\]'

PS1="${prompt_prefix}${PS1}${prompt_suffix}"
PS2="${prompt_prefix}${PS2}${prompt_suffix}"
PS3="${prompt_prefix}${PS3}${prompt_suffix}"
PS4="${prompt_prefix}${PS4}${prompt_suffix}"
