According to Andrey Dernov from JetBrains Support:

&gt; You use abbreviation added in keymap for quick search an action when &quot;Search everywhere&quot; (double Shift).

After adding &quot;foobar&quot; abbreviation to Git annotation command.

![enter image description here][1]

I can find the abbreviation and invoke the command with double Shift.

![enter image description here][2]

Unfortunately, the functionality does not support partial entry.

![enter image description here][3]

I personally find Shift-⌘-A easier to use in that case, because the results are limited to commands only.

PS: JetBrains support rocks!

Update: There was a follow-up from JetBrains:

&gt; The feature was recently added in IDEA, we haven&#39;t had time to update the documentation yet. We will do it in near future.

It is said that docker is not a VM and containers directly run on the host.

But why do containers need a base image OS ？

If process in containers run on the base image OS , what&#39;s the difference between a VM and docker(only the base image OS can be re-used and kept read-only?)

And why does it boot faster than a VM?

What makes up a base image OS ? kernel , rootfs or both?

Some of tasks I wrote start and never end. Ansible does not provide any errors or logs that would explain this, even with -vvvv option. Playbook just hangs and passing hours doesn&#39;t change anything.

When I try to run my tasks manually (by entering commands via SSH) everything is fine. 

Example task that hangs:

    - name: apt upgrade
      shell: apt-get upgrade

Is there any way to see stdout and stderr ? I tried:

    - name: apt upgrade
      shell: apt-get upgrade
      register: hello
    - debug: msg=&quot;{{ hello.stdout }}&quot;
    - debug: msg=&quot;{{ hello.stderr }}&quot;

but nothing changed.

I do have required permissions and I pass correct sudo password - other tasks that require sudo execute correctly.

What is the &quot;Abbreviation&quot; feature in IntelliJ IDEA Keymap for? [Web help on Keymap](http://www.jetbrains.com/idea/webhelp/keymap.html) is silent about it.

What is the IntelliJ IDEA&#39;s Keymap&#39;s abbreviation feature useful for?

<p>What is the "Abbreviation" feature in IntelliJ IDEA Keymap for? <a href="http://www.jetbrains.com/idea/webhelp/keymap.html" target="_blank" rel="noopener noreferrer">Web help on Keymap</a> is silent about it.</p>
<p><img src="http://i.stack.imgur.com/2LjMB.png" alt="IntelliJ Keymap abbreviation screenshot"></p>


    public class KV&lt;K, V&gt; {
        public K key;
        public V value;
        public KV(K key, V value) {
            this.key = key;
            this.value = value;
        } 
    }



I am trying to refactor the class variable `value`, which happens in place. That means no dialog pops up; I press enter and it tries to refactor across the entire project, including comments and what not, including:

    &lt;%--&lt;link href=&quot;&lt;c:url value=&quot;../core/core.css&quot; /&gt;&quot; /&gt;--%&gt;

in a .jsp file. That is way too &quot;clever&quot; to try to refactor **comments** that match across the entire project. This often causes lots of bug risk, and refactoring in a Java environment is no longer safe. 

The same thing was occurring in Intellij 12. Seriously, I don&#39;t need Intellij to recommend anything that is considered unsafe, or when it is not sure it is the same thing!

I can exclude the refactorings but I don&#39;t have time to evaluate five &quot;suggestions&quot; every time. It just raises the chance of human error: most of the time I just press enter, and woops things are refactored. 

Refactoring is also a major issue in a Java environment when it sometimes tries to replace things in .js files. Seriously, this has to stop. 

Without the popup dialog, I can&#39;t untick &quot;search strings&quot;. Even if that was ticked, Intellij should *never* include the suggestions by default, especially when it is outside the current file. It can recommend to refactor them as well, but they should be excluded by default. That is, it should be an opt-in feature, rather than by default destroying everything. 

This is a serious user experience problem with more recent so called &quot;smart&quot; Intellij refactoring. When refactoring JS files, I don&#39;t want to search Java files for comments or strings! Period! And vice versa! 

Safety comes first! Developers that know what they are doing will search for strings themselves if needed. In a dynamic language environment it makes Intellij impossible to use, because frequently, and without any clear pattern, sometimes refactorings go through, sometimes it changes things across the project and what not.

There should be an option that says, &quot;refactor only relative to this file or when 100% inferred!&quot;, especially for dynamic languages! For static languages it shouldn&#39;t even attempt to look for comments and strings outside the file. 

I didn&#39;t mean to put it out in public, but I have raised this issue over 2 years ago in the bugtracker, but nobody paid any attention.

**EDIT**

For those of you that think that I might be going to far, I just tried this out: 

With this class: 

    public class KV&lt;K, V&gt; {
        public K key;
        public V val;
        public KV(K key, V val) {
            this.key = key;
            this.val = val;
        }
    }

And adding this to **any** Java class, for instance: 

    public class CoreConfig {
        String abc = &quot;kv.val&quot;;
        String def = &quot;somethingElse.val&quot;;
    }


When refactoring `KV.val` as before, I get the following recommendations, an ENTER from disaster and something I have to evaluate and exclude one at a time. It takes effort and is just annoying and risky. It&#39;s like someone yelling out, STOP! And then ooh, nothing after a minute, frustration and a 1000 long word essay ( this ).

Seriously, is there a way to disable this kind of risky behaviour!? And is there any reason why this is on by default??

I have been attempting to run powershell as my terminal on windows in pycharm, so I did the following:

![enter image description here][1]

However, when I try this, it says that it cannot execute my scripts, and hence I get the following error: `SecurityError` and the Fully Qualified Id is : `UnAuthorizedAccess`.

This arises from the fact that pycharm&#39;s terminal cannot execute my `Powershell_profile.ps1` profile file.

How can I successfully run Pycharm&#39;s terminal with Powershell?

What I have tried so far, is going into my main powershell directory as in `%windir%/system32/WindowsPowerShell/1.0/profile.ps1`, and then change it to include the following:

    Set-ExecutionPolicy Unrestricted

However, this does not help, and I get the same error when I try to open of pycharm&#39;s terminal.

I have also tried to run pycharm as Admin, however this does not solve the problem either, and I get the _same_ aforementioned error.

I&#39;m trying to package a project using OptaPlanner 6.0.1 libraries into a .jar through IntelliJ IDEA&#39;s jar artifact but instead of my manifest.mf containing the standard

    Manifest-Version: 1.0
    Main-Class: a.b.c.app

the jar uses the one supplied in ecj-3.7.2.jar, one of OptaPlanner&#39;s supporting libraries:

    Manifest-Version: 1.0
    Build-Jdk: 1.6.0_26
    Built-By: ibrandt
    Created-By: Apache Maven
    Archiver-Version: Plexus Archiver

Because of this, a `&quot;no main manifest attribute, in appname.jar&quot;` error happens when trying to run the app. If I manually replace the manifest in .jar file with mine everything works correctly. Is there anything I can do to fix this?

I keep the libraries in a separate /lib directory and they were added to the root of jar artifact as Extracted Directory, IntelliJ IDEA is v13.0.1.





Wrong Manifest.mf in IntelliJ IDEA created .jar

It might be very trivial question, But I couldn&#39;t find any option to attach javadoc/source with local jar dependencies (in libs folder) in android project. I can&#39;t believe I have spent a hour on such simple stuff :( 

Google search result just tells about adding android documentation or adding javadoc in eclipse. That&#39;s not What I am looking for!

The default IntelliJ / Android Studio &quot;Redo&quot; action shortcut is &lt;kbd&gt;CTRL&lt;/kbd&gt;+&lt;kbd&gt;Shift&lt;/kbd&gt;+&lt;kbd&gt;Z&lt;/kbd&gt; and this is a common problem for Windows users.

A bigger problem is &lt;kbd&gt;CTRL&lt;/kbd&gt;+&lt;kbd&gt;Y&lt;/kbd&gt; is mapped to the &quot;Delete line&quot; action - and this causes the undo stack to be lost.

To solve this issue, how can the &quot;Redo&quot; shortcut be changed to &lt;kbd&gt;CTRL&lt;/kbd&gt;+&lt;kbd&gt;Y&lt;/kbd&gt; in IntelliJ?

Details:

* **IDE**: IntelliJ IDEA 14
* **O.S.:**: Windows 7

If I want to navigate to the **declaration** of a method I can choose one of the following approaches:

* press &lt;kbd&gt;Ctrl&lt;/kbd&gt; + left click
* right click &gt; Go To &gt; Declaration
* press &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;B&lt;/kbd&gt;

If I want to navigate to the **implementation** of a method I can choose one of the following approaches:

* press &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + left click
* right click &gt; Go To &gt; Implementation(s)
* press &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;B&lt;/kbd&gt;

In **Eclipse**, if I press &lt;kbd&gt;Ctrl&lt;/kbd&gt; and the mouse is over a method, a popup appears and I can choose what to do (go to Implementation/Declaration). If I press &quot;left click&quot; ( &lt;kbd&gt;Ctrl&lt;/kbd&gt; is still pressed ) the first option will be chosen.

I want to have the &#39;Ctrl&#39;+&#39;K&#39;,&#39;Ctrl&#39;+&#39;D&#39; functionality of Sublime in Android Studio, how do I do it?

&gt; Perfectly similar to this question, but with respect to Android Studio.
https://stackoverflow.com/questions/11548308/how-do-i-skip-a-match-when-using-ctrld-for-multiple-selections-in-sublime-text

I use **Ctrl+D** to add to selection (discrete multiple select) the next occurrence of the string (or substring) highlighted. And to skip adding next immediate selection to selection but the one after it, I use **Ctrl+K, Ctrl+D**. How do I do the same in Android Studio.

I just know Alt+J is similar to Ctrl+D (found from Keymappings in Android Studio). 

&gt; And to deselect the last selected it&#39;s Alt+Shift+D. 

But how do I skip next occurrence?

&gt;My question is in no way related to: 
https://stackoverflow.com/questions/12500502/does-intellij-idea-have-a-ctrl-k-ctrl-d-equivalent. That&#39;s Visual Studio equivalent. I want the SublimeText equivalent.
