Any time you delete a line in vi, it sends that line to an anonymous buffer. (yy yanks it into the anonymous buffer and p puts it back.) Yp works, also. The anonymous buffer is invisible to the user.

yy - yank (copy into anon buffer)
y - yank (same as above) p - put last buffered text after cursor
P - put last buffered text before cursor
dd - delete line (moves text into anon buffer)

Cursor movement (must be in command mode):

vi commands
h -left j -down k -up l -right	8j -Moves 8 down. 12h -Moves 12 to the left. - (dash) -Moves one line up. [RETURN] -One line down.
G -To beginning of last line. 1G -To beginning of line 1. #G -To beginning of #th line. $ -To the end of the line.	H -Head of window. M -Middle of window. L -Last of window. ^ -To first nonwhitespace character of line. 0 -To the 0 column of the line (absolute beginning).
w -To 1st character of next word. W -To beggining of next word, skipping punctuation. b -To beginning of previous word. B -To beginning of previous word, skipping punctuation. e -To end of next word. E -To end of next word, skipping punctuation.	[CTRL-d] -Scrolls down 1/2 screen. [CTRL-u] -Scrolls up 1/2 screen. [CTRL-f] -Scrolls down 1 screen. [CTRL-b] -Scrolls up 1 screen. x -Delete character that cursor is on. X -Delete from character that cursor is on to the beginning of the line.
dd -Delete entire line that cursor is on. D -Delete character the cursor is on and the rest of the line after. dw -Delete word cursor is on. 3dw -Delete next 3 words, starting where the cursor is. db -Delete word to right of character cursor is on.

Searching in vi:

/word: Finds 1st occurrence of word.
/[ENTER]: Repeat of last search command. (In this case, would find the next occurence of word.)
/word /[ENTER]: Finds the 1st occurrence of word searching backwards.
