Refactoring Keymap

Rationale

Make it easier to refactor using the keyboard by adjusting the default keymap to supercharge the Option + Command prefix for the most common refactoring actions.

Mechanism

Binding	Action	Default
Option + Command + A	Annotate
Option + Command + C	Extract Constant	Yes
Option + Command + I	Inline
Option + Command + J	Join Lines
Option + Command + L	Reformat Code	Yes
Option + Command + M	Extract Method	Yes
Option + Command + P	Extract Parameter	Yes
Option + Command + R	Rename
Option + Command + S	Split Vertically
Option + Command + T	Surround With...	Yes
Option + Command + U	Unwrap/Remove...
Option + Command + V	Extract Variable	Yes
Option + Command + Z	Analyze Stacktrace
Option + Command + Return	Last Edit Location
Option + Command + Up Arrow	Extend Selection
Option + Command + Down Arrow	Shrink Selection

Notes:

1. Some of these are the default bindings (as denoted by Yes in the Default column);
2. I remove the existing bindings (this may not work for you).
3. My starting keybinding in Mac OS X 10.5+.
