Sono sempre stato molto restio all'uso di emacs (ho sempre usato vi, anche perche' si trova dappertutto... emacs un po' meno).

Devo ammettere che pero' il binomio emacs-OCaml e' ottimo (penso che ci sia una cosa simile anche per il linguaggio R).

Ecco qui i comandi base di emacs (che devo studiarmi!): il C sta per control

Basic Editing

Starting Emacs

"emacs file" Opens emacs. "file" is either the name of the file you want to edit, or the new file you are creating.

C-x C-c

Quits emacs

C-g

Sometimes you can get all tripped up with commands, if you do, use this command to be put back in the text doc you were working on.

C-h

Online help. I suggest you use this. It is well written so newbies to emacs should seasily understand it.

C-x C-f

Opens a file into emacs.

C-x C-v

Open another file in place of the current one.

C-x C-s

Save

C-x C-w

Save as

C-x u

Undo. Multiple undo is supported in emacs.

C-x i

Inset a file at where the cursor (referred to as pointer by most emacs users)

Reading Usenet News with Gnus

Opening Gnus

You first open emacs (just type "emacs"), then type "M-x gnus", then hit return. Give it some time, it will have to download all your nesgroups. If you see it "Garbage collecting" just sit back for a minute. After emacs is done retrieving the newsgroups from your server you will see about 3 newsgroups displayed.

q

quits gnu news

s

saves the .newsrc file

A k

Lists all the newsgroups on the server. You will see a K in front of them, it stands for "kill", don't worry about it.

u

Subscribe or unsubscribe to currently highlighted newsgroup.

SPACE

Start reading the newsgroup the cursor (pointer) is on. You move through the newsgroups using the up and down arrows.

l (lowercase L)

Lists newsgroups that you have subscribed to.

SPACE

When you are reading a newsgroup, SPACE moves down a page at a time.

DEL

When you are reading a newsgroup the DEL key moves back one page at a time.

a

Create a news post, use it wisely.

F

Post a reply.

C-C C-C

Post the article.

q

When you are reading a newsgroup, q gets you back to the your list of newsgroups.
