An editor is presumably used for editing. If not, you could decide to not use
ne, because it just does that---it edits. It does not play
Tetris. It does not evaluate recursive functions. It does not solve your
love problems. It just allows you to edit.
The design of
ne makes editing extremely natural and straightforward.
There is no special thing to do in order to start---I assume that if you
start an editor, you want to edit, and not to give commands. Thus,
just press the keys of your keyboard, and see what happens.
ne provides two ways of deleting characters, bound to the
CONTROL-H, if you have no such key) and to
DELETE key respectively. In the former case you delete the
character at the left of the cursor, while in the latter you delete the
character just under the cursor. This is in contrast with many UN*X editors,
which for unknown reasons decide to limit your ways of destroying
things---something notoriously much funnier than creating. (see also
DeleteChar, and see Backspace).
If you want to delete a line, you can use the
DeleteLine command, or
CONTROL-Y. A very nice feature of
ne is that each time a
nonempty line is deleted, it is stored in a temporary buffer from which it can
be undeleted via the
UndelLine command, or
also DeleteLine, and see UndelLine).
If you want to copy, cut, paste or erase a block of text, you have to set a
mark. This is done via the
Mark command, activated by choosing the
Mark Block' item of the `
Edit' menu, or by pressing
CONTROL-B (=block). This command toggles the mark (puts it in
the current cursors position, or remove it). Whenever the mark is set, the
zone between the mark and the cursor can be cut, copied or erased. Note that
CONTROL-@ you can set a vertical mark instead,
that allows to cut exactly rectangles of text. Whenever a mark has been set,
M' appears on the command line; a `
V' appears instead if the
mark is vertical. If you forget where the mark is currently, you can use the
Goto Mark' menu item of the `
Search' menu in order to move to
cursor over it.
When you cut or copy a block, you can save it with the `
Save Clip...' menu
item of the `
Edit' menu. You can also load in memory a file with
Open Clip...', and paste it anywhere. All such operation act on the
current clip, which is by default the clip 0. You can change the current
clip number with the
ClipNumber command. See ClipNumber.
One of the most noteworthy features of
ne is its unlimited undo/redo capability. Each editing action is recorded, and can be played
back and forth as much as you like. Undo and redo are bound to the function
Another interesting feature is the possibility of loading an unlimited number
of documents. If you activate the
NewDoc command (using the
CONTROL-D or the command line), a new, empty
document will be created. You can switch between the existing documents in
F3, which are bound to the
NextDoc commands. If you have a lot of documents, the `
menu item prompts you with the list of names of currently loaded documents, and
allows you to choose directly what to edit.
