Help for using emacs.

Help for using emacs.

[Charlie]

Hi Guys, 
I used to use the emacs a lot when I was in college, and now I want to
pick it up after years. The emacs that I am using on Solaris is of
version: Xemacs 21.4(patch 9)  and these things are what I try to
recover

1. User starts emacs and opens more than one file. What is way to
switch from one to another. The way that I am using now, which is not
the quickest way, is "Ctrl X", "Ctrl B" to show the files in the
buffer and then pick the file that I am looking for.

2. User open a huge text file, what is the easist way to go to the end
of the file, not just keep typing "Ctrl -v" or "M-x end-of-buffer",
that I have to type that many letters to make it happen. And also if I
want to remove a large chunk of it, I know that we can highlight that
chunk from the beginning to the end, then type "Ctrl K" to remove it.
How ?

3. In a file to replace a keyword, I can do either "global replace" or
"replace it one after another". Can someone tells me how to do it in
the former way ?

4. Is there a website, menu,that tells all the "TRICKY" commands of
emacs ?

5. This is very common question I guess. Right now cross all the
platforms, the most popular edit tools being used are "vi" and
"emacs". I know a little about vi, which is used more common than
emacs!? So sometimes when I was trying to edit a file in my
colleague's machine, I find myself in a situation that emacs is not
available!!!
I am just wondering is there any other tools that I can use, or vi is
the only option.

 
thanks a lot!

You can use C-x b (do you remember the notation :-)?) to switch between 
buffers. When you invoke this command, a default buffer (the most 
recently visited one) name will be visible.  Hitting RET at this point 
will take you to that buffer.  Alternatively, you can enter the name of 
the buffer you really want to switch to and then hit RET.

Use M-> to go to the end and M-< to go to the beginning.

By "global replace", do you mean non-interactive replace? You can do M-% 
searchTerm RET and when asked about whether to replace a particular 
occurence, hit "!" (the exclamation mark).  This will automatically 
replace all occurence without asking you again.

Or you can simply do M-x replace-string.

I use Linux. Hopefully, it's the same.

C-x b. Don't use CTRL on the second b.

The keybindings have changed. It's now just like most programs. C-end. 
C-home if you want to go to the beginning.

M-x replace-regexp. This is an all-or-nothing, though. M-x query-replace 
will ask you as you go.

The Emacs website has a huge help file, but it can be tough slogging. I 
found O'Reilley's "Learning GNU Emacs" very helpful. It's still in print 
but it's somewhat out of date.

Never used Solaris. Sorry.

C-w (not C-k)

M-x replace-string

vi may be installed by the OS vendor (as may emacs), but you can always
install emacs yourself.

If your colleague's machine is available on the network, you can edit
files there from your own machine: C-x C-f /user@host:/dir/file RET

(see the Remote Files section of the online Emacs manual).

vi is not an option.

query-replace asks you a question, hitting ? there gives you help and
tells you that ! might do something you like.
