Quitting<\/strong><\/p>\n

: x Exit, saving changes
\n:q Exit as long as there have been no changes
\nZZ Exit and save changes if any have been made
\n:q! Exit and ignore any changes<\/p>\n

\nj Move down
\nk Move up
\nl Move right
\nw Move to next word
\nW Move to next blank delimited word
\nb Move to the beginning of the word
\nB Move to the beginning of blank delimted word
\ne Move to the end of the word
\nE Move to the end of Blank delimited word
\n( Move a sentence back

\nFc Move back to c
\nH Move to top of screen
\nM Move to middle of screen
\nL Move to botton of screen
\n% Move to associated ( ), { }, [ ]<\/p>\n

Deleting Text<\/strong>
\nAlmost all deletion commands are performed by typing d followed by a motion. For example, dw deletes a word. A few other deletes are:
\nx Delete character to the right of cursor
\nX Delete character to the left of cursor
\nD Delete to the end of the line
\ndd Delete current line
\n:d Delete current line<\/p>\n

Like deletion, almost all yank commands are performed by typing y followed by a motion. For example, y$ yanks to the end of the line. Two other yank commands are:
\nyy Yank the current line
\n:y Yank the current line<\/p>\n

Changing text<\/strong>
\nThe change command is a deletion command that leaves the editor in insert mode.
\nIt is performed by typing c followed by a motion. For example cw changes a word. A few other change commands are:
\nC Change to the end of the line
\ncc Change the whole line<\/p>\n

Putting text<\/strong>
\np Put after the position or after the line
\nP Put before the poition or before the line<\/p>\n

Buffers<\/strong>
\nNamed buffers may be specified before any deletion, change, yank or put command.
\nThe general prefix has the form “c where c is any lowercase character. for example,
\n“adw deletes a word into buffer a. It may thereafter be put back into text with an appropriate “ap.<\/p>\n

Markers<\/strong>
\nNamed markers may be set on any line in a file. Any lower case letter may be a marker name. Markers may also be used as limits for ranges.
\nmc Set marker c on this line
\n`c Go to beginning of marker c line.
\n‘c Go to first non-blank character of marker c line.<\/p>\n

Search for strings<\/strong>
\n\/string Search forward for string
\n?string Search back for string
\nn Search for next instance of string
\nN Search for previous instance of string<\/p>\n

Replace<\/strong>
\nThe search and replace function is accomplished with the :s command. It is commonly used in combination with ranges or the :g command (below).
\n:s\/pattern\/string\/flags Replace pattern with string according to flags.
\ng Flag – Replace all occurences of pattern
\nc Flag – Confirm replaces.
\n& Repeat last :s command<\/p>\n

Regular Expressions<\/strong>
\n. (dot) Any single character except newline
\n* zero or more occurances of any character
\n[…] Any single character specified in the set
\n[^…] Any single character not specified in the set
\n^ Anchor – beginning of the line
\n$ Anchor – end of line
\n\\< Anchor – begining of word \\> Anchor – end of word
\n\\(…\\) Grouping – usually used to group conditions
\n\\n Contents of nth grouping<\/p>\n

[…] – Set Examples [A-Z] The SET from Capital A to Capital Z
\n[a-z] The SET from lowercase a to lowercase z
\n[0-9] The SET from 0 to 9 (All numerals)
\n[.\/=+] The SET containing . (dot), \/ (slash), =, and +
\n[-A-F] The SET from Capital A to Capital F and the dash (dashes must be specified first)
\n[0-9 A-Z] The SET containing all capital letters and digits and a space
\n[A-Z][a-zA-Z] In the first position, the SET from Capital A to Capital Z
\nIn the second character position, the SET containing all letters<\/p>\n

Regular Expression Examples \/Hello\/ Matches if the line contains the value Hello
\n\/^TEST$\/ Matches if the line contains TEST by itself
\n\/^[a-zA-Z]\/ Matches if the line starts with any letter
\n\/^[a-z].*\/ Matches if the first character of the line is a-z and there is at least one more of any character following it
\n\/2134$\/ Matches if line ends with 2134
\n\/\\(21|35\\)\/ Matches is the line contains 21 or 35
\nNote the use of ( ) with the pipe symbol to specify the ‘or’ condition
\n\/[0-9]*\/ Matches if there are zero or more numbers in the line
\n\/^[^#]\/ Matches if the first character is not a # in the line
\nNotes:
\n1. Regular expressions are case sensitive
\n2. Regular expressions are to be used where pattern is specified<\/p>\n

Counts<\/strong>
\nNearly every command may be preceded by a number that specifies how many times it is to be performed. For example,
\n5dw will delete 5 words and 3fe will move the cursor forward to the 3rd occurence of the letter e.
\nEven insertions may be repeated conveniently with thismethod, say to insert the same line 100 times.<\/p>\n

Ranges<\/strong>
\nRanges may precede most “colon” commands and cause them to be executed on a line or lines.
\nFor example :3,7d would delete lines 3-7. Ranges are commonly combined with the :s command
\nto perform a replacement on several lines, as with :.,$s\/pattern\/string\/g to make a replacement from the current line to the end of the file.
\n:n,m Range – Lines n-m
\n:. Range – Current line
\n:$ Range – Last line
\n:’c Range – Marker c
\n:% Range – All lines in file
\n:g\/pattern\/ Range – All lines that contain pattern<\/p>\n

Files<\/strong>
\n:w file Write to file
\n:r file Read file in after line
\n:n Go to next file
\n:p Go to previos file
\n:e file Edit file
\n!!program Replace line with output from program<\/p>\n

Other<\/strong>
\n~ Toggle upp and lower case
\nJ Join lines
\n. Repeat last text-changing command
\nu Undo last change
\nU Undo all changes to line<\/p>\n
