scroll the text left-right to see all of a long line.  Switch wrapping off
with this command: >

	:set nowrap

Vim will automatically scroll the text when you move to text that is not
displayed.  To see a context of ten characters, do this: >

	:set sidescroll=10

This doesn't change the text in the file, only the way it is displayed.


WRAPPING MOVEMENT COMMANDS

Most commands for moving around will stop moving at the start and end of a
line.  You can change that with the 'whichwrap' option.  This sets it to the
default value: >

	:set whichwrap=b,s

This allows the <BS> key, when used in the first position of a line, to move
the cursor to the end of the previous line.  And the <Space> key moves from
the end of a line to the start of the next one.

To allow the cursor keys <Left> and <Right> to also wrap, use this command: >

	:set whichwrap=b,s,<,>

This is still only for Normal mode.  To let <Left> and <Right> do this in
Insert mode as well: >

	:set whichwrap=b,s,<,>,[,]

There are a few other flags that can be added, see 'whichwrap'.


VIEWING TABS

When there are tabs in a file, you cannot see where they are.  To make them
visible: >

	:set list

Now every tab is displayed as ^I.  And a $ is displayed at the end of each
line, so that you can spot trailing spaces that would otherwise go unnoticed.
   A disadvantage is that this looks ugly when there are many Tabs in a file.
If you have a color terminal, or are using the GUI, Vim can show the spaces
and tabs as highlighted characters.  Use the 'listchars' option: >

	:set listchars=tab:>-,trail:-

Now every tab will be displayed as ">---" (with more or less "-") and trailing
white space as "-".  Looks a lot better, doesn't it?


KEYWORDS

The 'iskeyword' option specifies which characters can appear in a word: >

	:set iskeyword
<	  iskeyword=@,48-57,_,192-255 ~

The "@" stands for all alphabetic letters.  "48-57" stands for ASCII
characters 48 to 57, which are the numbers 0 to 9.  "192-255" are the
printable latin characters.
   Sometimes you will want to include a dash in keywords, so that commands
like "w" consider "upper-case" to be one word.  You can do it like this: >

	:set iskeyword+=-
	:set iskeyword
<	  iskeyword=@,48-57,_,192-255,- ~

If you look at the new value, you will see that Vim has added a comma for you.
   To remove a character use "-=".  For example, to remove the underscore: >

	:set iskeyword-=_
	:set iskeyword
<	  iskeyword=@,48-57,192-255,- ~

This time a comma is automatically deleted.


ROOM FOR MESSAGES

When Vim starts there is one line at the bottom that is used for messages.
When a message is long, it is either truncated, thus you can only see part of
it, or the text scrolls and you have to press <Enter> to continue.
   You can set the 'cmdheight' option to the number of lines used for
messages.  Example: >

	:set cmdheight=3

This does mean there is less room to edit text, thus it's a compromise.
