To create a custom key bindings file goto XCode>Preferences>Bindings> Duplicate an existing binding and name it whatever you want then go to and open the file you just created in a text editor so you can see the xml output.

~/Library/Application Support/Xcode/Key Bindings/*.pbxkeys

A good list of available commands can be found here

1. Duplicate code!

I can't believe xcode doesn't have this in Eclipse you simple select your text and press Ctrl + Alt and either Up or Down on the keypad and it will duplicate your code placing it either above or below the current selection. It will also reselect the newly duplicated code so that you can duplicate it as many times as you like.

  var a : uint = b + ( 10024-200 ) / 2;//195ms
√ var a : uint = b + 412;//47ms
 

Multiplication is faster than Division
nice explanation of using multiplication for division here

 
  result = num / 4;//382ms
√ result = num * 0.25;//132ms
 

Use Implicit type casting

 
  var a : Point = points[ i ] as Point;//179ms
√ var a : Point = points[ i ];//109ms
 

Test variables before methods in statements

 
  if(method( ) && variable )//211ms
√ if( variable && method() )//7ms
 

Declare varialbes outside of loops

 
for( var i : int = 0; i < arr.length; i ++ )//515ms
  var i : int = 0;
  var arrLength : int = arr.length;
√ for( ; i < arr.length; i ++ )//39ms
 

Thowing erors takes time.

 
  try{ isNull.x = 3; }catch( e : Error ){ }//78ms
√ if( isNull ) { isNull.x = 3; }//0ms
 

Use references instead of full paths or the with operator.

 
  with( sprite.graphics ){ ...};//164ms
√ var g : Graphics = sprite.graphics;//23ms
 

Use Object Pools

Bitwise tricks
Bitwise maths on wikipedia Boolean algebra on wikipedia

val = num | 0; //Same as Math.floor();
val = num + 0.5 | 0; // Rounds positive numbers.
//Divide by power of two
val = num >>1; //Divide by 2 and floor.
val = num / 32 is the same as val = num >> 5
val = 65535 >> 8; //255
//actual value is 255.996...
//But it is being floored as well
i = (x^(x>>31)) - (x>>31);//about 2700% faster than Maths.abs();
 
if(++count&1){}//alternation i need to check this one.
 

Simply create a class that throws an error in the constructor. This will cause the browser to crash and close.

 
 
package
{
   public class BrowserCrasher
   {
      public function BrowserCrasher( )
      {
         throw new Error( 'goodbye browser' );
      }
   }
}
 

I found a couple posts on the subject.

org.eclipse.jface.text;bundle-version="3.4.1",
com.adobe.flexbuilder.editors.common;bundle-version="3.0.214193"

This re-enabled the plugin for me. Great!

Another little tip with working with snippets and workspaces:
when switching workspaces you lose all your snippets as they are kept in the workspaces .metadata/.plugins/org.cfeclipse.cfml/snippets
this folder is recreated for each new workspace you create. So what i do is keep a global snippets folder in my main workspace and simply replace the snippets folder in my other workspaces with a simlink to the main one. That way when ever i add a new snippet it is shared across all my workspaces.

just a little side note:: if you don't know how to show hidden files in mac osx. type the following into the terminal and then restart finder.

defaults write com.apple.Finder AppleShowAllFIles TRUE

To turn it off set it to false. You also need to restart Finder for it to take effect.
Also if you don't know how to create the simlink you simple go into the terminal, navigate to your workspace then .metadata>.plugins>org.cfeclipse.cfml delete the snippets folder that is in there and then type
ln -s PATH TO YOUR WORKSPACE WHERE YOU KEEP YOUR MAIN SNIPPET FOLDER/snippets Snippets

This should then put a simlink inside your workspace and you can then share your snippets across all your workspaces instead of having to copy them into each.
