This wuold be a simple reminder for the most common tips for VI or VIM.
It would not be a deep dive on it, simply a memo for the most common feature used by me.
Search and replace a string in a document :
:.,$s/search_string/replacement_string/g
Disabling highlighted patterns :
Type “:nohl” to disable highlighting
Comment out several lines at once (I like that one) :
1. Ctrl + V (visual block)
2. Select the lines you want to be commented out
3. Shift + I (insert mode)
4. Add the “#” character on the first line
5. Press escape
Copy and paste several lines :
1. Shift + V (visual line)
2. Select the lines
3. Press “yyN” (N lines yanked), for example to copy 3 lines use “yy3″
4. Go where you want the block to be pasted and press “p”
Cut and paste several lines :
1. Let’s say you want to cut 3 lines, put your cursor on the first of the 3 lines
2. Type : 3dd
3. Locate your cursor where you want the block to be pasted
4. Type “p”
Some key combinations :
dd : Delete current line
D : Delete from cursor to end of line
d$ : Delete from cursor to end of line
d0 : Delete from cursor to beginning of line
dw : Delete from cursor to end of current word
db : Delete from cursor to beginning of current word
yy : Copy current line (use “p” to paste)
Here’s a great cheatsheet from http://www.worldtimzone.com/res/vi.html
Cursor movement
* h – move left
* j – move down
* k – move up
* l – move right
* w – jump by start of words (punctuation considered words)
* W – jump by words (spaces separate words)
* e – jump to end of words (punctuation considered words)
* E – jump to end of words (no punctuation)
* b – jump backward by words (punctuation considered words)
* B – jump backward by words (no punctuation)
* 0 – (zero) start of line
* ^ – first non-blank character of line
* $ – end of line
* G – Go To command (prefix with number – 5G goes to line 5)
Note: Prefix a cursor movement command with a number to repeat it. For example, 4j moves down 4 lines.
Insert Mode – Inserting/Appending text
* i – start insert mode at cursor
* I – insert at the beginning of the line
* a – append after the cursor
* A – append at the end of the line
* o – open (append) blank line below current line (no need to press return)
* O – open blank line above current line
* ea – append at end of word
* Esc – exit insert mode
Editing
* r – replace a single character (does not use insert mode)
* J – join line below to the current one
* cc – change (replace) an entire line
* cw – change (replace) to the end of word
* c$ – change (replace) to the end of line
* s – delete character at cursor and subsitute text
* S – delete line at cursor and substitute text (same as cc)
* xp – transpose two letters (delete and paste, technically)
* u – undo
* . – repeat last command
Marking text (visual mode)
* v – start visual mode, mark lines, then do command (such as y-yank)
* V – start Linewise visual mode
* o – move to other end of marked area
* Ctrl+v – start visual block mode
* O – move to Other corner of block
* aw – mark a word
* ab – a () block (with braces)
* aB – a {} block (with brackets)
* ib – inner () block
* iB – inner {} block
* Esc – exit visual mode
Visual commands
* > – shift right
* < – shift left
* y – yank (copy) marked text
* d – delete marked text
* ~ – switch case
Cut and Paste
* yy – yank (copy) a line
* 2yy – yank 2 lines

* p – put (paste) the clipboard after cursor
* P – put (paste) before cursor
* dd – delete (cut) a line
* dw – delete (cut) the current word
* x – delete (cut) current character
Exiting
* :w – write (save) the file, but don’t exit
* :wq – write (save) and quit
* :q – quit (fails if anything has changed)
* :q! – quit and throw away changes
Search/Replace
* /pattern – search for pattern
* ?pattern – search backward for pattern
* n – repeat search in same direction
* N – repeat search in opposite direction
* :%s/old/new/g – replace all old with new throughout file
* :%s/old/new/gc – replace all old with new throughout file with confirmations
Working with multiple files
* :e filename – Edit a file in a new buffer
* :bnext (or :bn) – go to next buffer
* :bprev (of :bp) – go to previous buffer
* :bd – delete a buffer (close a file)
* :sp filename – Open a file in a new buffer and split window
* ctrl+ws – Split windows
