There is no shortcut assigned, but you can easily assign a new one:

Go to `IDE settings | Keymap | Main menu | Window | Editor Tabs | Reopen Closed Tab` (type `reopen` into the filter field to find it faster), right click on that item and select `Add Keyboard Shortcut`

Update: As stated in another answer, you can also use &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;E&lt;/kbd&gt; to see a list of all recently viewed files. Additionally, you can use &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;E&lt;/kbd&gt; to see a list of all recently **edited** files, which is handy when working on multiple files.

For Windows -&gt; &lt;kbd&gt;ctrl&lt;/kbd&gt;+&lt;kbd&gt;e&lt;/kbd&gt;

For macOS -&gt; &lt;kbd&gt;cmd&lt;/kbd&gt;+&lt;kbd&gt;e&lt;/kbd&gt;

It will show a popup window for the files you visited previously.

The shortcut is &lt;kbd&gt;cmd&lt;/kbd&gt;&lt;kbd&gt;[&lt;/kbd&gt; (&lt;kbd&gt;Ctrl&lt;/kbd&gt;&lt;kbd&gt;Alt&lt;/kbd&gt;&lt;kbd&gt;←&lt;/kbd&gt; on Windows). It correspond to `Navigate` &gt; `Back`.

It will bring your cursor where it was previously, re-opening the tab if needed, and you can do it many times.

You may don&#39;t have to google this thing.

There are some shortcut given in Android Studio Screen :) :)

### Important note: this has been accepted as a [Spring issue](https://jira.spring.io/browse/SPR-12349) with a target fix version of 4.1.2.

---------
My goal is to achieve O(1) space complexity when generating an HTTP response from Hibernate&#39;s `ScrollableResults`. I want to keep the standard mechanism where a `MessageConverter` is dispatched to handle an object returned from a `@Controller`. I have set up the following:

1. `MappingJackson2HttpMessageConverter` enriched with a `JsonSerializer` which handles a Java 8 `Stream`;
2. a custom `ScrollableResultSpliterator` needed to wrap `ScrollableResults` into a `Stream`;
3. `OpenSessionInViewInterceptor` needed to keep the Hibernate session open within the `MessageConverter`;
4. set `hibernate.connection.release_mode` to `ON_CLOSE`;
5. ensure that the JDBC connection has the necessary ResultSet holdability: `con.setHoldability(ResultSet.HOLD_CURSORS_OVER_COMMIT)`.

Additionally, I need a database which supports that kind of holdability. PostgreSQL is such a database and I have no trouble with this.

The final stumbling point I have encountered is the policy used by `HibernateTransactionManager` on transaction commit: unless the underlying session is &quot;Hibernate-managed&quot;, it will `disconnect()` it, closing my cursor along with everything else. Such a policy is useful in some special scenarios, specifically &quot;conversation-scoped sessions&quot;, which  are far removed from my requirements.

I have managed to work around this with a bad hack: I had to override the offending method with a method which is effectively a copy-paste of the original except for the removed `disconnect()` call, but it must resort to reflection to access private API.

    public class NoDisconnectHibernateTransactionManager extends HibernateTransactionManager
    {
      private static final Logger logger = LoggerFactory.getLogger(NoDisconnectHibernateTransactionManager.class);
    
      public NoDisconnectHibernateTransactionManager(SessionFactory sf) { super(sf); }
    
      @Override
      protected void doCleanupAfterCompletion(Object transaction) {
        final JdbcTransactionObjectSupport txObject = (JdbcTransactionObjectSupport) transaction;
        final Class&lt;?&gt; c = txObject.getClass();
        try {
          // Remove the session holder from the thread.
          if ((Boolean)jailBreak(c.getMethod(&quot;isNewSessionHolder&quot;)).invoke(txObject))
            TransactionSynchronizationManager.unbindResource(getSessionFactory());
    
          // Remove the JDBC connection holder from the thread, if exposed.
          if (getDataSource() != null)
            TransactionSynchronizationManager.unbindResource(getDataSource());
    
          final SessionHolder sessionHolder = (SessionHolder)jailBreak(c.getMethod(&quot;getSessionHolder&quot;)).invoke(txObject);
          final Session session = sessionHolder.getSession();
          if ((Boolean)jailBreak(HibernateTransactionManager.class.getDeclaredField(&quot;prepareConnection&quot;)).get(this)
              &amp;&amp; session.isConnected() &amp;&amp; isSameConnectionForEntireSession(session))
          {
            // We&#39;re running with connection release mode &quot;on_close&quot;: We&#39;re able to reset
            // the isolation level and/or read-only flag of the JDBC Connection here.
            // Else, we need to rely on the connection pool to perform proper cleanup.
            try {
              final Connection con = ((SessionImplementor) session).connection();
              DataSourceUtils.resetConnectionAfterTransaction(con, txObject.getPreviousIsolationLevel());
            }
            catch (HibernateException ex) {
              logger.debug(&quot;Could not access JDBC Connection of Hibernate Session&quot;, ex);
            }
          }
          if ((Boolean)jailBreak(c.getMethod(&quot;isNewSession&quot;)).invoke(txObject)) {
            logger.debug(&quot;Closing Hibernate Session [{}] after transaction&quot;,  session);
            SessionFactoryUtils.closeSession(session);
          }
          else {
            logger.debug(&quot;Not closing pre-bound Hibernate Session [{}] after transaction&quot;, session);
            if (sessionHolder.getPreviousFlushMode() != null)
              session.setFlushMode(sessionHolder.getPreviousFlushMode());
          }
          sessionHolder.clear();
        }
        catch (ReflectiveOperationException e) { throw new RuntimeException(e); }
      }
    
      static &lt;T extends AccessibleObject&gt; T jailBreak(T o) { o.setAccessible(true); return o; }
    }

Since I regard my approach as the &quot;right way&quot; to generate ResultSet-backed responses, and since the Streams API makes this approach very convenient, I would like to solve this in a supported way.

Is there a way to get the same behavior without my hack? If not, would this be a good thing to request via Spring&#39;s Jira?

Trouble using ScrollableResults-backed Stream as return type in Spring MVC

I try to underline part of a string, for example, a &#39;*string*&#39; part in &#39;*test string*&#39; string. I&#39;m using `NSMutableAttributedString` and my solution was working well on `iOS7`.

    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]
            initWithString:@&quot;test string&quot;];
    [attributedString addAttribute:NSUnderlineStyleAttributeName
                             value:@(NSUnderlineStyleSingle)
                             range:NSMakeRange(5, 6)];
    myLabel.attributedText = attributedString;


The problem is that my solution is not working in `iOS8` anymore. After spending an hour on testing multiple variants of `NSMutableAttributedString`, I found out that this solution works only when range starts with 0 (length can differ). What is the reason for that? How can I workaround this?

I have received a Security Alert from Google this week that tells me to upgrade my android version of cordova app. The email from google is as below - 

&gt; This is a notification that your --apps ids--, is built on a version of Apache Cordova that contains security vulnerabilities. This includes a high severity cross-application scripting (XAS) vulnerability. Under certain circumstances, vulnerable apps could be remotely exploited to steal sensitive information, such as user login credentials.
&gt;
&gt; You should upgrade to Apache Cordova 3.5.1 or higher as soon as possible. For more information about the vulnerabilities, and for guidance on upgrading Apache Cordova, please see http://cordova.apache.org/announcements/2014/08/04/android-351.html.
&gt;
&gt; Please note, applications with vulnerabilities that expose users to risk of compromise may be considered “dangerous products” and subject to removal from Google Play.


So, I needed to check the current version of my cordova apps. I can upgrade my cordova installation by using `npm update -g cordova` on windows cmd. The question is how can I check the current platform (android in my case) version of my cordova app?

I could not run the android application never on my laptop. Eclipse gives same error constantly, that is &quot;ADB server didn&#39;t Acknowledge&quot;

I&#39;ve tried everything, restart adb from ddms view, from command line (kill-server, start-server), from task manager and restart eclipse. When I manage to start adb server and re-open eclipse, as soon as I run the android application, same error comes to console; ADB server didn&#39;t ack.

Could you give an idea except restarting adb

From *[Create dynamic lists with RecyclerView][1]*:

When we create a `RecyclerView.Adapter` we have to specify `ViewHolder` that will bind with the adapter.

    public class MyAdapter extends RecyclerView.Adapter&lt;MyAdapter.ViewHolder&gt; {

        private String[] mDataset;

        public MyAdapter(String[] myDataset) {
            mDataset = myDataset;
        }

        public static class ViewHolder extends RecyclerView.ViewHolder {
            public TextView mTextView;
            public ViewHolder(TextView v) {
                super(v);
                mTextView = v;
            }
        }

        @Override
        public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.some_layout, parent, false);

            //findViewById...

I saw a lot of examples for `.gitignore` files for **AndroidStudio**, some have `.idea` in them, and some don&#39;t.

Is there a good reason not to add the entire .idea dir to .gitignore?

If it should not be completely ignored, are there specific files inside .idea (such as .iml) that should be in .gitignore? 

Android studio - should the entire .idea directory be in git ignore?

So I am new to Android development and Android Studio.

I used Android Studio to create an Android project, and each time I wanted to commit the code to GitHub, I switched over to the command line and committed/pushed the code from there. 

However, I realize now that Android Studio has it&#39;s own features for connecting to GitHub. I&#39;d like to use those features. 

Since the project already exists, I prefer not to just create a new GitHub repository from Android Studio and delete the old one. I just want to connect the existing GitHub repository with the Android Studio project.

How can I sync these up?

Is it possible to some how setup IntelliJ IDEA so that I can column select with the cursor keys similarly to how I might in Notepad++, Visual Studio, or FlashDevelop.

For instance when I&#39;m typing code I almost always do my navigation solely through use of the keyboard. In the IDEs mentioned previously I can quickly select blocks of code by holding &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; then tapping &lt;kbd&gt;↑&lt;/kbd&gt; to extend my cursor across the lines above. I can then hold &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;Ctrl&lt;/kbd&gt; and tap &lt;kbd&gt;←&lt;/kbd&gt; or &lt;kbd&gt;→&lt;/kbd&gt; to quickly jump across words and select the chunk of text I want.

In IntelliJ IDEA I have to constantly enable and disable Column Selection Mode using the &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;Insert&lt;/kbd&gt; and even then it doesn&#39;t quite function as it does in the other IDEs or Text Editors.

Any ideas?

I don&#39;t know if it is bug or kind of setting, but it is very annoying while typing value i.e.   `android:layout_gravity=&quot;&quot;`, it opens hints with dropdown, and after a while the documentation view gets opened and hides the dropdown with hints.

I can finally ask a question to get my points up.  

In android studio, I want to be able to override the method, however I do not know the keyboard shortcut.  Does anyone know? 

How to override method via keyboard shortcut in Android Studio

I&#39;m having issues with Xcode being quite unreliable when using the keyboard shortcut to comment or uncomment code &lt;kbd&gt;⌘&lt;/kbd&gt;+&lt;kbd&gt;/&lt;/kbd&gt;. I can&#39;t seem to find a real pattern as to when it breaks, but it usually happens after building and running my code on the simulator. It will not work again until I edit something in any one of my code files. Even if I switch to another file in the main view, commenting via shortcut does not work. Other keyboard shortcuts, such as indenting &lt;kbd&gt;⌘&lt;/kbd&gt;+&lt;kbd&gt;[&lt;/kbd&gt; continue to work just fine.

Do other people have this issue, and if so, have you found a solution? I know it seems like a small complaint, but when running and then quickly trying to comment out a block of code to check the effect, it&#39;s a bit of an inconvenience.

I am using Xcode 6.1 (6A1052d) on OXS Yosemite 10.10 (14A389) and developing in Objective-C for iOS if that matters.

How to move to previous caret position in Android Studio

I know that I can jump to the beginning and end of a line inside the OS X terminal with &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;A&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;E&lt;/kbd&gt;. But I&#39;m so used to jumping with &lt;kbd&gt;Cmd&lt;/kbd&gt;+&lt;kbd&gt;Right&lt;/kbd&gt; arrow and &lt;kbd&gt;Cmd&lt;/kbd&gt;+&lt;kbd&gt;Left&lt;/kbd&gt; arrow from my editor, that I would love to use these shortcuts for the terminal too.

I haven&#39;t found a solution with Google, so maybe here someone can help.

**Update**

As in the comments, I tried the solution from https://stackoverflow.com/questions/81272/is-there-any-way-in-the-os-x-terminal-to-move-the-cursor-word-by-word/81299#81299
