In your .emacs place `(setq-default fill-column 80)` Or you can just use M-x customize-variable on fill-column, and it will set it and save it for you using the standard customize interface.

Is there a best practice / recommendation when I want to use a variable declared outside of a function when it comes to using:

1. `global $myVar`
2. `$GLOBALS[&#39;myVar&#39;]`

Thank you.

PHP global or $GLOBALS

I have this HTML which looks like this:

    &lt;input type=&quot;submit&quot; name=&quot;savebutton&quot; class=&quot;first button&quot; /&gt;
    &lt;input type=&quot;submit&quot; name=&quot;savebutton&quot; class=&quot;second button&quot; /&gt;

and JS:

    jQuery(&quot;input.second&quot;).click(function(){
       // trigger second button ?
       return false;
    });

So how can I trigger the click event from the 2nd button by clicking on the first one?
Note that I don&#39;t have any control over the 2nd button, neither on the html or the click event on it...

I know that &quot;C-u 80 C-x f&quot; sets the fill width 80, and M-q adjusts it.
How to make it default? I mean, how to make width 80 deafault for fill width?

How to set the default width of fill mode to 80 with emacs?

I need to get the full path of the file that I&#39;m editing with emacs.

 * Is there a function for that?
 * If not, what would be the elisp function for getting that?
 * How can I copy the result (path name) to a clipboard so that I can reuse it?

I&#39;m using Mac OS X and Aqumacs. 

    (setq filepath (get-fullpath-current-file)) ???
    (copy-to-clipboard &#39;filepath) ???

## ADDED
&lt;pre&gt;
(defun show-file-name ()
  &quot;Show the full path file name in the minibuffer.&quot;
  (interactive)
  (message (buffer-file-name))
  (kill-new (file-truename buffer-file-name))
)
(global-set-key &quot;\C-cz&quot; &#39;show-file-name)
&lt;/pre&gt;

Combining the two answers that I got, I could get what I want. Thanks for the answers. And some more questions.

 * What&#39;s for (file-truename)?
 * Can I copy the path name to System(OS)&#39;s clipboard, not the kill ring so that I can use the info with the other apps?

The function to show current file&#39;s full path in mini buffer

I need to concatenate path string as follows, so I added the following lines to my `.emacs` file:

    (setq org_base_path &quot;~/smcho/time/&quot;)
    (setq org-default-notes-file-path (concatenate &#39;string org_base_path &quot;notes.org&quot;))
    (setq todo-file-path (concatenate &#39;string org_base_path &quot;gtd.org&quot;))
    (setq journal-file-path (concatenate &#39;string org_base_path &quot;journal.org&quot;))
    (setq today-file-path (concatenate &#39;string org_base_path &quot;2010.org&quot;))

When I do &lt;kbd&gt;C-h v&lt;/kbd&gt; `today-file-path` &lt;kbd&gt;RET&lt;/kbd&gt; to check, it has no variable assigned. 

What&#39;s wrong with my code? Is there any other way to concatenate the path string?

## EDIT
I found that the problem was caused by the wrong setup, the code actually works. Thanks for the answers which are better than my code.

Concatenate strings in elisp

I&#39;ve learned Clojure previously and really like the language. I also love Emacs and have hacked some simple stuff with Emacs Lisp. There is one thing which prevents me mentally from doing anything more substantial with Elisp though. It&#39;s the concept of dynamic scoping. I&#39;m just scared of it since it&#39;s so alien to me and smells like semi-global variables. 

So with variable declarations I don&#39;t know which things are safe to do and which are dangerous. From what I&#39;ve understood, variables set with setq fall under dynamic scoping (is that right?) What about let variables? Somewhere I&#39;ve read that let allows you to do plain lexical scoping, but somewhere else I read that let vars also are dynamically scoped. 

I quess my biggest worry is that my code (using setq or let) accidentally breaks some variables from platform or third-party code that I call or that after such call my local variables are messed up accidentally. How can I avoid this? 

Are there a few simple rules of thumb that I can just follow and know exactly what happens with the scope without being bitten in some weird, hard-to-debug way?


How to live with Emacs Lisp dynamic scoping?

What is the emacs equivalent of vi&#39;s &lt;kbd&gt;dd&lt;/kbd&gt;? I want to delete the current line. Tried &lt;kbd&gt;CTRL&lt;/kbd&gt; + &lt;kbd&gt;k&lt;/kbd&gt; but it only deletes _from_ current position.  

How can I delete the current line in Emacs?

I&#39;d like to use 2 spaces for my indents instead of 4. I can change the default behavior of C mode using: 

    (setq c-basic-offset 2)

How do I change this in javascript mode?
