change command (in this case, "df>"). To delete another tag, position the
cursor on the < and use the "." command.
To <B>generate</B> a table of <B>contents ~
f< find first < --->
df> delete to > -->
f< find next < --------->
. repeat df> --->
f< find next < ------------->
. repeat df> -->
The "." command works for all changes you make, except for "u" (undo), CTRL-R
(redo) and commands that start with a colon (:).
Another example: You want to change the word "four" to "five". It appears
several times in your text. You can do this quickly with this sequence of
commands:
/four<Enter> find the first string "four"
cwfive<Esc> change the word to "five"
n find the next "four"
. repeat the change to "five"
n find the next "four"
. repeat the change
etc.

*04.4* Visual mode
To delete simple items the operator-motion changes work quite well. But often
it's not so easy to decide which command will move over the text you want to
change. Then you can use Visual mode.
You start Visual mode by pressing "v". You move the cursor over the text you
want to work on. While you do this, the text is highlighted. Finally type
the operator command.
For example, to delete from the middle of a word to the middle of another:
This is an examination sample of visual mode ~
---------->
velllld
This is an example of visual mode ~
When doing this you don't really have to count how many times you have to
press "l" to end up in the right position. You can immediately see what text
will be deleted when you press "d".
If at any time you decide you don't want to do anything with the highlighted
text, just press <Esc> and Visual mode will stop without doing anything.
SELECTING LINES
If you want to work on whole lines, use "V" to start Visual mode. You will
see right away that the whole line is highlighted, without moving around.
When you move left or right nothing changes. When you move up or down the
selection is extended whole lines at a time.
For example, select three lines with "Vjj":
+------------------------+
| text more text |
>> | more text more text | |
selected lines >> | text text text | | Vjj
>> | text more | V
| more text more |
+------------------------+
SELECTING BLOCKS
If you want to work on a rectangular block of characters, use CTRL-V to start
Visual mode. This is very useful when working on tables.
name Q1 Q2 Q3
pierre 123 455 234
john 0 90 39
steve 392 63 334
To delete the middle "Q2" column, move the cursor to the "Q" of "Q2". Press
CTRL-V to start blockwise Visual mode. Now move the cursor three lines down
with "3j" and to the next word with "w". You can see the first character of
the last column is included. To exclude it, use "h". Now press "d" and the
middle column is gone.
GOING TO THE OTHER SIDE
If you have selected some text in Visual mode, and discover that you need to
change the other end of the selection, use the "o" command (Hint: o for other
end). The cursor will go to the other end, and you can move the cursor to
change where the selection starts. Pressing "o" again brings you back to the
other end.
When using blockwise selection, you have four corners. "o" only takes you to
one of the other corners, diagonally. Use "O" to move to the other corner in
the same line.
Note that "o" and "O" in Visual mode work very differently from Normal mode,
where they open a new line below or above the cursor.

*04.5* Moving text
When you delete something with "d", "x", or another command, the text is
saved. You can paste it back by using the "p" command. (The Vim name for
this is put).
Take a look at how this works. First you will delete an entire line, by
putting the cursor on the
