Depends on the editor. On vi, it's the ts (tabstop) option:
:set ts=4
On some terminals, you can change the tab stops of a terminal
via some escape sequences. See the "tabs" command form the GNU
termutils for instance:
$ tabs -4 | od -c
0000000 \r 033 [ 3 g \r 033 H 033 H
0000020 033 H 033 H 033 H
0000040 033 H 033 H
0000060 033 H 033 H 033 H
0000100 033 H 033 H 033 H
0000120 033 H 033 H
0000140 033 H 033 H 033 H
0000160 033 H 033 H 033 H
0000200 033 H 033 H
0000220 033 H 033 H 033 H
0000240 033 H 033 H 033 H
0000260 033 H 033 H
0000300 033 H 033 H 033 H
0000320 033 H 033 H \r

Thanks, How to I get that to stick as my default settings (In both
Vista and Ubuntu).
Thanks again. |

Put it in your editor configuration file. For vi, put:
set ts=4
in your ~/.exrc
If you want to change the settings of the terminal for good,
it may be done in the configuration of the terminal for some
(check their manual) or you can use something like the "tabs"
command in your shell startup file.

....well, OP said "move", not "insert". He can do (depending on the flavor
of vi-clone), map the tab-character to a movement command, in command-mode,
or insert-mode. So I'd suggest reading the description of "map" and related
commands.

What the heck is that? In my Debian GNU/Linux tabs-command has this
path:
/opt/heirloom/5bin/tabs
I have installed heirloom Toolchest from source code. GNU Termutils has
this WWW-page:
http://www.gnu.org/software/termutils/
Oh, no! I must suggest Debian-project to package that.

Amen.
Vim will do this for you using:
set expandtabs ts=4
Why spaces instead of TABs. Because when I print my work, the
printer is going to use columns of 8 when printing real TABs.
This makes my output like like crap.
YES, and because of THAT, you should probably use this instead:
set expandtabs ts=8 sw=4 ai si
Leave hard tabs as 8, so that they will print properly. Shiftwidth will
make sure the code indents as you expect.

The option is expandtab, not expandtabs. |

As others have mentioned ts=4 in vi and Vim will cause the editor
to display a TAB on column of 4 boundaries.
HOWEVER, after years and years of working with TABs in text files,
I have found that it is much MUCH better to just eliminate the use
of the TAB character, and instead get your editor to insert the
correct number of spaces. Vim will do this for you using:
set expandtabs ts=4
Why spaces instead of TABs. Because when I print my work, the
printer is going to use columns of 8 when printing real TABs.
This makes my output like like crap.
When my code is edited by fellow developers, if they use a
different perferred ts setting (or just take their editor's
default), my code will look like crap to them (which will reflect
badly against me in their eyes). Worst they may modify code and
make it look pretty using their column of 8 TABs and when I get my
code back, it will look like crap to me.
If I use 'more' or 'less' on the file, it will look like crap.
Spaces will look the same regardless of whether printed, or viewed
in anyones preferred text editor/viewer.
NOTE: If you are using Vim, and you do not care about anyone else
that might view your files, and you do not intend to print your
files, etc..., then you could use Vim mode lines to lock in your
ts settings. Just put a comment within 5 lines of the beginning
or end of your file containing:
/* vim: ts=4 expandtabs */
where /* ... */ are C source comments. Use the commenting
convention that matches the kind of file you are editing.
NOTE 2: I turn use noexpandtabs when I'm editing a file that
requires tabs as separators, such as Makefiles

In which terminals you can do it? It seems that at least terminal types
xterm and xterm-256color do not support that.

Yes, xterm supports it. Such a command was in Unix V7 30 years
ago, so I suppose it's widely supported. It's the hts (set_tab)
terminfo capability, ts in termcap.
$ TERM=xterm-256color tput hts | od -c
0000000 033 H
0000002
But beware that we're talking of the
/hardware/ (terminal) tab stops. Many applications (vi, bash,
zsh) will implement them in "software", that is, for display,
will send spaces instead of tab characters. You need to
configure those applications to tell them as far appart you want
the tab stops to be.
Try it running the "cat" command for instance.

any vt100-compatible can do this; there's a test-screen in vttest whic
illustrates it.
