Configure Home/End Key Bidings on Mac OS X

Hi I feel that this  a prety common request: Bind the Home/End keys to move to the beginning and end of lines respectively.

In Mac OS X (10.5 and 10.6) some applications use the Cmd-Rigt and Cmd-Left to perform these actions but, call me old fashioned, I like to use Home and End instead.

It is actually very easy to change the Cocoa Key bindings for any user under Mac OS. Just follow these steps:

1. Create a file called DefaultKeyBinding.dict in ~/Library/KeyBindings directory

   mkdir ~/Library/KeyBindings
   cd ~/Library/KeyBindings
   touch DefaultKeyBinding.dict

2. Edit your DefaultKeyBinding.dict file so it contains:

   {
   /* home */
   "\UF729"  = "moveToBeginningOfLine:";
   "$\UF729" = "moveToBeginningOfLineAndModifySelection:";
   
   /* Cmd-Left */
   "@\UF702"  = "moveToBeginningOfLine:";
   "$@\UF702" = "moveToBeginningOfLineAndModifySelection:";
   
   /* Cmd-Right */
   "@\UF703"  = "moveToEndOfLine:";
   "$@\UF703" = "moveToEndOfLineAndModifySelection:";
   
   /* end */
   "\UF72B"  = "moveToEndOfLine:";
   "$\UF72B" = "moveToEndOfLineAndModifySelection:";
   
   /* page up/down */
   "\UF72C"  = "pageUp:";
   "\UF72D"  = "pageDown:";
   }

3. Restart the Cocoa Application.

This example works very well with TextMate.

In order to bind other keys you need to find their Scan code, and you can use the following modifiers
