# searching
/joe/e : cursor set to End of match
/joe/e+1 : cursor set to End of match plus 1
/joe/s-2 : cursor set to Start of match minus 2
/^joe.*fred.*bill/ : normal
/^[A-J]\+/ : search for lines beginning with one or more A-J
/begin\_.*end : search over possible multiple lines
/fred\_s*joe/i : any whitespace including newline
/fred\|joe : Search for FRED OR JOE
/\([^0-9]\|^\)%.*% : Search for absence of a digit or beginning of line
/.*fred\&.*joe : Search for FRED AND JOE in any ORDER!
/\<fred\>/i : search for fred but not alfred or frederick
/\<\d\d\d\d\> : Search for exactly 4 digit numbers
/\D\d\d\d\d\D : Search for exactly 4 digit numbers

# Repeating the Regexp (rather than what the Regexp finds)
/^\([^,]*,\)\{8}
# visual searching
:vmap // y/<C-R>"<CR> : search for visually highlighted text
:vmap <silent> // y/<C-R>=escape(@", '\\/.*$^~[]')<CR><CR> : with spec chars

In regular expressions you must backslash ( (group)
In regular expressions you must backslash { (count)

Part II: Additional VIM Tips added by WiKi Users
replace tabs with 2 spaces
:1,$s/\(^I\)/ /g
note: the ^I is the result of simply pressing the TAB key. That is the escape code for a TAB.
tell vim to insert spaces when the tab key is pressed
set expandtab set tabstop=2 retab
note: the tabstop tells vim how many spaces to use for a tab, and the retab changes all the tabs you entered before turning on expandtab into spaces.
parameter in your text files telling vim how to render file
vim: textwidth=80
note: put this at the bottom of the text file. when you open the file in vim it will set the width to 80 columns for that file.
Disable automatic comment insertion
If wanted, auto commenting can be disabled for all files with:
:set noautoindent | set nosmartindent | set nocindent
Create a .vimrc for your shell and put the lines in like this
set noautoindent set nosmartindent set nocindent
or to Disable auto commenting just for paste operations temporarily while working in a file
:set paste
Disable annoying bracket highlighting aka bracket match aka parentheses match
Using the ":syntax off" doesn't disable bracket match, such as you would see when working with HTML tags. The problem is that the highlighting is terrible on some terminals such as Konsole. To disable type
:NoMatchParen
The matchparen plugin has become enabled on your installation. You can run the :NoMatchParen command to shut it off. ":he matchparen" has instructions for how to disable it altogether. You can also find out where 'showmatch' might be getting set by setting the 'verbose' option to non-zero or using the ":verbose" command. You can see ":he :set-verbose" for more info on that one. Colors for the matching bracket or brace can be customized by adding to the .vimrc file.
hi MatchParen cterm=none ctermbg=green ctermfg=blue
reference: turning off showmatch
Use vim as a HEX Editor
The vim editor does not have a HEX Edit mode, but can stream the buffer to an external program called xxd.
Open the file with the -b command line switch (Binary mode. A few options will be set that makes it possible to edit a binary or executable file.)
vi -b binaryfile
Now stream the buffer to xxd from within vim
:%!xxd
And when your done and want to exit the redirect
:%!xxd -r
If you are at the command prompt you can display the hex output of a binary file simply by typing
xxd binaryfile
This demonstrates how you are actually using xxd from within vim
