Pressing &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;A&lt;/kbd&gt; toggles Block or Column selection mode in Eclipse 3.5 or later.

Other than that you can try the &#39;Columns 4 Eclipse&#39; Plug-in for Eclipse 3.3.1 [here](http://columns4eclipse.sourceforge.net/).

As another poster noted- the Android ADT blocks the use of Alt+Shift+A. An easy fix is to go to `Window-&gt;Preferences-&gt;General-&gt;Keys` and look for &quot;Toggle Block Selection&quot;

From there, you can assign your own hotkey that will not conflict with the Android tools. For example I tied it to Alt+A, which works just fine.

As others have said, this will not work in Eclipse 3.4 or earlier. I am using Eclipse 3.7.2, YMMV.

For the Mac, use &lt;kbd&gt;⌥&lt;/kbd&gt;&lt;kbd&gt;⌘&lt;/kbd&gt;&lt;kbd&gt;A&lt;/kbd&gt; (option+command+A) to toggle between the two selection modes.  Command-Shift-A will give you something quite unexpected.

What kind of language is CSS?

My first inclination was to call it a markup language... but it doesn&#39;t really fit the mold:

&gt; A markup language is a system for
&gt; annotating a text in a way which is
&gt; syntactically distinguishable from
&gt; that text. -[wikipedia][1]

CSS uses various selectors to apply properties to elements *within* HTML, a markup language

Imagine we have an enum:

    enum Foo { A=1,B=2,C=3 }

If the type is known at compile-time, a direct cast can be used to change between the enum-type and the underlying type (usually `int`):

    static int GetValue() { return 2; }
    ...
    Foo foo = (Foo)GetValue(); // becomes Foo.B

And boxing this gives a box of type `Foo`:

    object o1 = foo;
    Console.WriteLine(o1.GetType().Name); // writes Foo

(and indeed, you can box as `Foo` and unbox as `int`, or box as `int` and unbox as `Foo` quite happily)

***However*** (the problem); if the enum type is only known at runtime things are... trickier. It is obviously trivial to box it as an `int` - but can I box it as `Foo`? (Ideally without using generics and `MakeGenericMethod`, which would be ugly). `Convert.ChangeType` throws an exception. `ToString` and `Enum.Parse` works, but is *horribly* inefficient.

I could look at the defined values (`Enum.GetValues` or `Type.GetFields`), but that is very hard for `[Flags]`, and even without would require getting back to the underlying-type first (which isn&#39;t as hard, thankfully).

But; is there a more direct to get from a value of the correct underlying-type to a box of the enum-type, where the type is only known at runtime?

In Microsoft tools such as Word and Visual Studio, there is a feature to select text in a rectangle manner by pressing the Alt key while selecting. Is there anything like that in Eclipse?

In Eclipse, is there a way you can set Method Breakpoints on all the methods of the class without going to individual methods? The motivation behind is that, any time a method gets hit, it would go to that method in debug mode.

Suppose I know a function name, but I don&#39;t know which file it&#39;s declared in. What Eclipse keyboard shortcut can take me to the function I&#39;m looking for?


----------


What I&#39;m looking for is similar to Eclipse&#39;s: 

&lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;R&lt;/kbd&gt; 

except it will search for method names instead.


----------

Sidenote
--------

With Visual Assist X, I can do this by using the &quot;Find Symbol&quot; feature, which is executed with:

&lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;S&lt;/kbd&gt;

I&#39;ve been running STS 2.3.2 on a MacBook Pro for a few days now. I&#39;m finding the performance to be significantly slower than any other build of Eclipse I&#39;ve used. For example, switching from one tab to another can take up to 4 seconds.

I tried turning off much of the validation, and increasing the memory, but it&#39;s not making a difference.

Are others having similar experiences?

Why is SpringSource Tool Suite (STS) so slow? And how can I fix it?

I have a few really long strings in one class for initializing user information. When I compile in Eclipse, I don&#39;t get any errors or warnings, and the resulting .jar runs fine.

Recently, I decided to create an ant build file to use. Whenever I compile the same class with ant, I get the &quot;constant string too long&quot; compile error. I&#39;ve tried a number of ways to set the java compiler executable in ant to make sure that I&#39;m using the exact same version as in Eclipse.

I&#39;d rather figure out how to get the same successful compile I get in Eclipse in Ant than try to rework the code to dynamically concatenate the strings.

Background
----------

I&#39;m working on an application which requires user-entered content, and I&#39;ve decided to use a Stack Overflow-style Markdown editor. After researching this topic for the last few days, I realize there are numerous forks of the base WMD editor, some with a few basic enhancements and some with serious differences from the Stack Overflow one.

Since this will be the heart of the application, I&#39;d like to start with the best code base I can. I&#39;d be happy if anyone can recommend which one of the many solutions out there best fits my needs.

Below are requirements, plus what I&#39;ve managed to find already. I&#39;m hoping this question will help me decide which version to go with, and maybe help me discover a port that&#39;s an even better fit for my needs.

----------

The requirements for my project
-------------------------------

 - Live preview
 - Multiple editors on the same page (I do not know how many in advance, since the user can dynamically add another editing box).
 - Ability to extend with extra buttons (I&#39;d like a button to upload a picture, instead of just adding an `img` URL).
 - Ability to dynamically show/hide the edit box (and only see the preview box).
 - Not an absolute must, but I&#39;d prefer to stick as close to Stack Overflow&#39;s look and feel, since it&#39;s well known.
 - Don&#39;t know if this matters, but the backend is written in Django.

Editors I&#39;ve looked at
----------------------

Here are a few of the code bases I&#39;ve looked at, with thoughts. Obviously, I might be missing another solution out there.

 - The [derobins][1] version. From what I can tell, this is the official Stack Overflow version. Seems like it doesn&#39;t support multiple editors on one page.
 - [jQuery.MarkEdit][2]. Looks very good, but is pretty different from the Stack Overflow version.
 - [MooWMD][3]. Looks like the winner right now, but I&#39;m a little concerned since it looks less active/hackable than MarkEdit.
 - The [wmd-new][4] version. Not sure, looks like an old codebase without much use.
 - The [SocialSite branch][5]. Seems like it&#39;s not for public use.

Does anyone program with white text against black background? I have heard some rumors that it is better for your eyes. What&#39;s the case? Is it any better than the traditional black on white? What are the pros and cons?

I would like to search multiple files via eclipse for the following 2 lines:

    @Length(max = L_255)
    private String description;
    
and replace them with these two:

    @Length(max = L_255, message=&quot;{validator.description.len}&quot;)
    private String description;



How to search and replace 2 lines (together) in Eclipse?

As I&#39;m always dissatisfied with existing editors, a project I always wanted to start is my own text editor. However doing text editing is serious business.

Besides analyzing the source code of existing text editors, is there any book or other resource (like academic work) about this topic? I&#39;m interested especially in something that teaches how to handle memory and how to manage text insertion (if you have a 100 MB file and want to add a char at *x* position, you can&#39;t just `memmove` the huge text block...).

Is there any simple SQL editor in Eclipse? Or do I need to find a simple SQL editor plugin for Eclipse?

By simple I mean, the editor does **NOT** connect to any DB, does syntax highlighting and preferably formatting sql is a bonus.
