`#` is simply an Ex special character that will be replaced with the name of the alternate file. Do an `:ls`, and the alternate file will be marked with a `#` there also.

`#` can similarly be used with `:tabnew` and `split`. In the examples below I&#39;ll use `:tabe` in place of `:tabnew` as `:tabe` is a shorter alias for `:tabnew` (search for either in the help docs):
 
- To open the alternate file in a new tab: `:tabe#`
- To open the file in a new split: `:split#`; this can be abbreviated to `:sp#`, and `:vsp#` for a vertical split.

Using a buffer _number_ from `:ls`, e.g. buffer number _5_ you can also:

- open the buffer in a split with `:sp#5`; alternately `:sb5` if the `switchbuf` option contains the `newtab` specifier - see `:help switchbuf`
- open the buffer in a vertical split with `:vsp #5` (there is no `:vsb`)
- open the buffer in a new tab with `:tabe #5`



You don&#39;t necessarily have to leave normal mode to open the alternate buffer in a new window:

&lt;kbd&gt;CTRL&lt;/kbd&gt;-&lt;kbd&gt;W&lt;/kbd&gt; &lt;kbd&gt;^&lt;/kbd&gt; **opens the alternate buffer in a horizontal split**.

&lt;kbd&gt;CTRL&lt;/kbd&gt;-&lt;kbd&gt;W&lt;/kbd&gt; &lt;kbd&gt;T&lt;/kbd&gt; opens the current buffer in a new tab (Shift-T, that is).

So, one solution to your title question is the following combo.

&lt;kbd&gt;CTRL&lt;/kbd&gt;-&lt;kbd&gt;W&lt;/kbd&gt; &lt;kbd&gt;^&lt;/kbd&gt;, &lt;kbd&gt;CTRL&lt;/kbd&gt;-&lt;kbd&gt;W&lt;/kbd&gt; &lt;kbd&gt;T&lt;/kbd&gt;: **opens the alternate buffer in a new tab.**

Note that for the caret &quot;^&quot; in the first command you don&#39;t have to release the Control key and you don&#39;t have to press Shift, just hold down &lt;kbd&gt;CTRL&lt;/kbd&gt; then strike &lt;kbd&gt;W&lt;/kbd&gt; and &lt;kbd&gt;6&lt;/kbd&gt; (where the caret is located on many English keyboard layouts).

When including the factory_bot_rails gem in your dev and test blocks in Gemfile, rails will generate factories automatically when your models are generated. 

Is there a way to generate factories after your models have been generated?

This is a really basic question, but I&#39;m trying to change the favicon of my node.js/Express app with

    app.use(express.favicon(__dirname + &#39;/public/images/favicon.ico&#39;));

and I&#39;m still getting the default favicon. This is in my `app.configure` function, and yes, I&#39;ve verified that there **is**  a `favicon.ico` in the `/public/images/favicon.ico`.There&#39;s nothing about a `favicon.ico` in the console, either, which leads me to believe that this line of code is being ignored. Everything else in the function (setting port, setting views directory, setting template engine. etc.) seems to be working fine, so why would this line of code not be executing?

**What I tried**

 - Emptying browser cache
 - Restarting Terminal and running `node app.js` again
 - Adding `{ maxAge: 2592000000 }`, as described [here](https://groups.google.com/forum/?fromgroups#!topic/express-js/W5mkAorVrW8)

Thanks in advance.

**Update:** I got it to work. See my answer below for more information.

I know I can open the last closed (`:q`) file in Vim by using `:e#`. This will open the file in the current tab. How would I perform the same task but open the file in a new Vim tab. Also I am interested in how to open the file in a new split instead of the current tab.

I am running slitaz distro, and would like to completely remove the root password. I have tried giving a blank password to the `passwd` command, however that did not seem to do the trick. It gave me an error password was too short, ans it still asked me for a password when I ssh-ed in. The password was just hiting the &quot;Enter&quot; key.

**UPDATE:**  
Perhaps it has to do with the fact that slitaz uses dropbear for ssh? Because even with a blank password for root in `/etc/shadow`, it still prompts for a password.

Setup : Ubuntu Server on Virtual Machine with 6 cores and 3GB of RAM.

when I am trying to generate a `asymmetric key pair` via `GPG` like this `gpg --gen-key` . I get the following error :

    Not enough random bytes available.  Please do some other work to give
    the OS a chance to collect more entropy!
I tried to google a little bit. This is what I realise , 
I need to fire up another terminal and type in `cat /udev/random` --&gt; It randomly generates a series of randomly generated values to increase the entropy. 

I dont see any change in here `watch cat /proc/sys/kernel/random/entropy_avail`

and it still persists to give me the same error

I&#39;d like to add to PATH the value &quot;:/home/me/play/&quot;  
for the installation of Play! framework.  
so I ran this command:  

    PATH=$PATH:/home/me/play

it worked. but in the next time I checked, the value changed back to the old one.  

so I guess I didn&#39;t &quot;saved&quot; the new value, right?  

how do you do that?

I&#39;ve been trying Vim for any text editing work for almost a week now. I want to know the fastest way to select a C function definition.

For example, if I have a function like this:

```c
void helloworlds( int num )
{
    int n;
    for ( n = 0; n &lt; num; ++n ) {
        printf( &quot;Hello World!\n&quot; );
    }
}
```

How would I be able to delete the whole definition including the function name?

`:30` will move my cursor to the beginning of line 30.

How can I tell Vim to place the cursor at line y, column x? Is this possible
without using the arrow keys or `h`, `j`, `k`, `l` keys?

I am running Vim version 7.3.429.

I started to use gvim, and I can&#39;t quite understand how the multiline edit works in gvim.

For example:

Original text:

    asd asd asd asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;

ctrl+q, jjjjjj , $
everything is selected, then i press I to do a multiline insert.

My intention is to insert quotes like in the first line, and then to press Esc:

    asd &quot;asd asd&quot; asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;
    asd asd asd asd asd;

What happened? I expected a behavior similar to sublimetext&#39;s one:

![enter image description here][1]

If you don&#39;t know how that works, it just repeats the actions for every line. How can achieve that? And what is vim doing here?

How do I exit the Vim editor?

In normal text editors [with all due respect to Vim] there is a shortcut &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;Z&lt;/kbd&gt; when you have done something nasty and want to return to the previous version of the text. Like BACK button in Word. I wonder how can you achieve this behaviour in Vim.

In vi/vim editor, I need to copy a block. There are many ways, but one way is very quick.

1. label the first line by some way,

2. then label the end line by some way,

3. then put some command to copy the labeled lines.

4. then copy, may using &#39;p&#39;, but not sure.

Anybody know the commands (not yy or 10yy)? Thanks in advance.

Is there a way to profile Vim plugins?

I have bundles ultisnips and youcompleteme installed on my macvim.
The problem is that ultisnips doesn&#39;t work because tab is bound by ycm.
I tried putting `let g:UltiSnipsExpandTrigger = &quot;&lt;s-tab&gt;&quot;` so that I can trigger the snippet completion with shift-tab, but it doesn&#39;t work for some unknown reason. I could use caps as the trigger, but so far I&#39;ve found no way to do that.

Do any of you use those two add-ons together?
What can I do to make shift-tab work?
Can you recommend another key to trigger snippets?

I am using OS X 10.9.1 (Mavericks).

What are the systematic steps to install to Gvim or MacVim in Mac OS? If you write the steps using 1, 2, 3, ..., it would be easy to follow. 

I must confess that I failed to understand all the instructions provided on MacVim page. Other google-searched webpages do not clarify. 
E.g. 

What is `$VIMRUNTIME` ? 
What version of vim should I install for my OS? 

Now somehow I have installed MacVim in my system (Not systematically I believe).
I can see that I have a folder `/Applications/gvim.app/MacVim.app/`. 

Now when I open a text file from MacVim, which was already written using vi-editor, MacVim does not recognize it. Also vi does not recognize whatever is written in MacVim! 

How can I resolve this?
