Emacs and vim analogs

Emacs and vim analogs

[-- Attachment #1.1: Type: text/plain, Size: 718 bytes --]

I've been bouncing back and forth between Vim and Emacs for some time, and
lately I've been trying to reconcile the abilities of one with the other.
Specifically, I'm wondering if there is something in Emacs analogous to the
following Vim capabilities.

1) Omni-completion.  Here, if you're happily typing something and come
across a name, function call, etc, that you have typed before, in Vim you
can press Ctrl+N to see what can go with what you've typed so far.
Moreover, in many cases, it does this intelligently, taking syntax into
account.
2) Redo-last-change.  In Vim, if you make a change, pressing "." will make
the change again.  Is there something analogous in Emacs, aside from
defining a macro?

Thanks!

Either C-x M-ESC or C-x z, depending on your requirements.

I do not know actually, since I always use Viper in Emacs ;-)

But see the page http://www.emacswiki.org/cgi-bin/wiki/ViAndEmacs

You probably mean C-x ESC ESC or C-x M-: . C-x M-ESC simply quits my
emacs. But both are not doing what '.' does in vim. With vims . you
can repeate commands like “replace next three word with …”, “indent 5
lines”, “append … to line” or “replace rest of line with …” 
(where … stands for some text). This is not possible with emacs
because there is no implicit grouping of inserted characters, so C-x z
repeats the last character typed, which is completely useless.

While I use the . command in vim frequently, I never ever had any use
for “repeat” or “repeat-complex-command” (I can't even think of a
usefull application for “repeat”).

The statement "This is not possible with emacs" is typically false.

Complex commands such as you describe are easily done with keyboard 
macros.  There are so useful that I have the start, end, and execute 
functions assigned to function keys.

Or you can use Viper mode in Emacs. At least in Emacs 22 (pretest) it is 
very good.
