5.0 - What's online at the vi archives?
There is a FAQ posted frequently which gives a list of all the files
that are online at the vi archive. It also gives a list of addresses
which mirror the vi archive. The main address is ftp://alf.uib.no/pub/vi, but it is
archived at many, many sites. The vi-archive faq lists all of them.
Please check that faq before ftping to it, as there is almost definitely
a closer and therefore faster site to you than the one in Norway.
A few mirrors are: ftp://ftp.uwp.edu/pub/vi
ftp://ftp.uu.net/pub/text-processing/vi.
ftp://ftp.cc.monash.edu.au/pub/vi
ftp://ftp.s.u-tokyo.ac.jp/misc/vi-archive
The site has many, many files on vi, including a few clones. It also
has the UCB distribution of vi, and lots of useful macros. Check it
out.
6.0 - Silly vi tricks, and silly macros
This section is for silly vi tricks, and silly macros. Actually, any
interesting vi tricks and macros are acceptable, as long as they are
not too lengthy. I will add any that are suggested to me that I think
are reasonable.
6.1 - Silly vi tricks
Note: Also check out the Silly macros down below. Many macros and
tricks are interchangable.
xp This will delete the character under the cursor, and put it
afterwards. In other words, it swaps the location of two characters.
ddp Similar to xp, but swapping lines.
yyp duplicate a line
uu Undo and redo last change. (This will take you to the last
modification to the file without changing anything.) You can also use
this to compare the changes to a line. Make the changes to the line,
press U to undo the changes to the current line, and then press u to
toggle between the two versions.
:g/.*/m0
This will reverse the order of the lines in the current file.
m0 is the ex command to move the line to line 0.
:v/./d or :g/^$/d
Removes all blank lines.
:g/^[ <ctrl-v><tab>]*$/d
Removes all lines that only have whitespace.
:v/./.,/./-1join
Replaces multiple blank lines with just one blank line.
6.2 - Silly macros
Note: <ctrl-x> means hold down control, and hit x.
Swap character and one vertically above:
map * kxjphxkP
Fold a line that's too long
map g $80<ctrl-v><ctrl-v>|F r<ctrl-v><enter>
Change case on most words
map v ywmno<ctrl-v><esc>P:s/./\~/g<ctrl-v><enter>0"nDdd`n@n
Put `and' around the current word
map *` i`<ctrl-v><esc>ea'<ctrl-v><esc>
Put 'and' around the current word
map *' i'<ctrl-v><esc>ea'<ctrl-v><esc>
Put "and" around the current word
map *" i"<ctrl-v><esc>ea"<ctrl-v><esc>
Put `and' around the current word
map! `` <ctrl-v><esc>bi`<ctrl-v><esc>ea'
Split a line at the cursor, and put a > at the beginning of the next
line. (For quoting Usenet, etc). I had some trouble with my old
version of this under some versions, so I've redone it, and I think
that it should work.
map g may0O<ctrl-v><esc>P`ao<ctrl-v><esc>P:s/./ /g<ctrl-v><enter>0i><ctrl-v><esc>$mb`ay$`bP'add
Insert one character
map g i$<ctrl-v><esc>r
Format a paragraph without the fmt program. (To use, use J a few
times, then this a few times)
map K 072lBhr<ctrl-v><enter>
Or, a little less elegantly, but without the need to use J and K Make ctrl-x work as cut, ctrl-v as paste, ctrl-p as copy. You should Save a read-only file. Careful, it changes the permissions.

Command mode is the mode within vi where the user gives commands to
vi. (Including cursor movement commands, editing commands, etc.)
A non-visual editor under unix.
The escape key. A key on a keyboard normally marked by escape.
Sometimes ^[ will work in its place. If there is no escape key,
sometimes the Meta key will work.
An editor under unix, all commands preceded with : are passed to
it.
Insert mode is the mode within vi where text is inserted into the
document.
A macro is a shortcut key combination. For example, a macro allows
one to hit one letter and have it execute a few different commands.
Open mode is the mode that vi will start in if it cannot determine
your terminal type, or if it believes you have a hardware or glass-tube
terminal.
Regular expressions, commonly known as "RegEx" or "REs" are a set
of key combinations that are meant to allow people to have a large
variety of control over what they are searching for. RegEx is used a
lot under Unix, and is common between many programs.
Stream editor. An editor that has no interface. All commands
are given from the command line.
