UTF-8 is a character encoding that can represent the whole ISO 10646
character set—two billion characters! ne
can load and
manipulate UTF-8 files transparently, in particular on systems that
provide UTF-8 I/O. See UTF-8 Support.
It often happens that you have to browse through a file, switching frequently
between a small number of positions. In this case, you can use
bookmarks. There are up to ten bookmarks per document, each designated
by a single digit, with the default being '0'. You can set them with the
SetBookmark
command, and you can return to any set bookmark with the
GotoBookmark
command. Also, ne
sets an automatic bookmark
(designated by '-') to your current position in a document whenever you
use the GotoBookmark
command. You can use this automatic bookmark to
return to that previous location with a GotoBookmark -
command. Doing
so will reset the automatic bookmark, so that subsequent GotoBookmark -
commands will switch between those two locations. See SetBookmark,
GotoBookmark, and UnsetBookmark. Note that in the default
configuration no key binding is assigned to these commands. If you use them
frequently, you may want to change the key bindings. See Key Bindings.
ne
will detect automagically the presence of MS-DOS line terminators
(CR/LFs) and set the CR/LF flag. When the file will be saved, the
terminators will be restored correctly. You can change this behaviour
using the PreserveCR
and CRLF
commands. See PreserveCR,
and CRLF.
ne
allows a simplified form of binary editing. If the
binary flag is set, only NULLs are considered newlines when loading or
saving. Thus, binary files can be safely loaded, modified and saved.
Inserting a new line or joining two lines has the effect of inserting or
deleting a NULL. Be careful not to mismatch the state of the binary flag
when loading and saving the same file.
The NoFileReq
command deactivates the file requester. It is
intended for “tough guys” who always remember the names of their files and can
type them at the speed of light (maybe with the help of the completer,
which is activated by the <Tab> key; see The Input Line).
There are three ways to execute un*x commands from within ne
.
The System
command can run any un*x command; you
will get back into ne
as soon as the command execution terminates.
See System. The Through
(<Meta>-T) command (which can be found in the
'Edit' menu), however, is much more powerful; it cuts the current
block, passes it as standard input to any un*x command, and pastes the
command's output at the current cursor position. This provides a neat
way to pass a part of your document through one of un*x's many
filter commands (commands that read from standard input and write
to standard output, e.g., sort
). See Through. Finally, you can use the
Suspend
(<Control>-Z) command to temporarily stop ne
and
return to your command shell. See Suspend.

, see
