In insert mode, `Ctrl-o` escapes user to do one normal-mode command, and then return to the insert mode. The same effect can be achieved by `&lt;ESC&gt;`ing to normal mode, doing the single command and then entering back to insert mode. `Ctrl-i` is simply a `&lt;Tab&gt;` in insert mode.

In normal mode, `Ctrl-o` and `Ctrl-i` jump user through their &quot;jump list&quot;, a list of places where your cursor has been to. The jumplist can be used with the quickfix feature, for example to quickly enter to a line of code containing errors.

Is there a way to do a project wide search and replace in netbeans? It seems like there should be, but I can not find any information on it.

Thanks

I&#39;ve followed [Railscast #235](http://railscasts.com/episodes/235-omniauth-part-1) to try and set up a minimal Facebook authentication.

I&#39;ve first set up a Twitter authentication, as done by Ryan himself. That worked flawlessly.

I then moved on to adding a Facebook login. However, after authorizing the app the redirect to `/auth/facebook/callback` fails with:

    SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

I am working on localhost. I didn&#39;t set up any SSL within the app. What am I doing wrong?

What do they do, and how do you use them? Any tips / tricks would also be appreciated.

I&#39;m aware of opening files in readonly mode from shell using `vim -R`, but how to open a file from inside vim in a separate tab (`:tabe &lt;filename&gt;`) in readonly mode?

Thanks for your time.

The main scrolling commands in Vim are:  

 1. &lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;B&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;F&lt;/kbd&gt;, as well as &lt;kbd&gt;PageUp&lt;/kbd&gt; and &lt;kbd&gt;PageDown&lt;/kbd&gt; scroll by full page  
 2. &lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;U&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;D&lt;/kbd&gt; scroll half a page by default  
 3. &lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;Y&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;E&lt;/kbd&gt; scroll one line

I lose visual context every time for the former two, so I have developed the bad habit of hitting the latter (&lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;Y&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt;-&lt;kbd&gt;E&lt;/kbd&gt;) repetitively.  

Since there is currently no first party support for smooth scrolling, what are the least objectionable workarounds/plugins?

I use both Vim and GVim depending on the task, and am happy to customize them separately if there is no one really good hack that works for both. The mouse scroll wheel works nicely in GVim, but I&#39;m looking for keyboard based solutions.

What is the best way to do smooth scrolling in Vim?

I don&#39;t often have to modify multiple commit messages, but it has happened once or twice and I don&#39;t ever remember seeing this. I hope someone else has. When I `git rebase -i HEAD~7`, the expected list opens in vi exactly as expected. I change the `pick` values to `edit` where appropriate and then `:wq`.

&gt; Could not execute editor

The `core.editor` setting in my global `.gitconfig` is `vi` (I&#39;ve also changed it to `vim` in a wildly desperate move). I tried using `mate`, but that didn&#39;t even open the initial list properly so I changed it back.

I&#39;m using v1.7.3 and would welcome any suggestions.

In vim, FIXME and TODO are highlighted, but I can&#39;t get FIXME: and TODO: (note the colon after the keyword) to highlight? What should I put in my .vimrc to make this happen?

I&#39;m switching over from Eclipse to IntelliJ. In Eclipse, if you do &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;O&lt;/kbd&gt; in the editor, it will show a hover popup that allows you to search for a method in the class you&#39;re editing.

What is the equivalent shortcut for that in IntelliJ?

I know that &lt;kbd&gt;Esc&lt;/kbd&gt; + &lt;kbd&gt;.&lt;/kbd&gt; gives you the last argument of the last command.

But I&#39;m interested in first argument of the last command.
Is there a key binding to do so?

On the same lines, is there a generic way of getting the nth argument from the last command?
I know that in a bash script, you can use `$0`, `$1` etc., but these don&#39;t work on the commandline.

**Also, what about iterating through the 0th argument of previous commands, like we can do with the last argument by continuously pressing &lt;kbd&gt;Esc&lt;/kbd&gt; + &lt;kbd&gt;.&lt;/kbd&gt;?**

Is there a shortcut key in Visual Studio that will minimize all of the regions or + signs so that I don&#39;t have to go through and click each one individually?

In Eclipse, selecting a line and pressing &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;&amp;uarr;&lt;/kbd&gt;/&lt;kbd&gt;&amp;darr;&lt;/kbd&gt; will move the line up and down, a quick way to avoid copy&amp;paste.
Is there an equivalent in Visual Studio?

If I am in split-screen viewing 2 different buffers on Emacs and the cursor is on the top buffer, what&#39;s a quick way to move the cursor to the bottom buffer?

Bonus question: if I know a command, is there an easy way to identify what key-combo it&#39;s bound to, if any?
