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 Lines	Yes
Option + Command + M	Extract Method	Yes
Option + Command + P	Extract Parameter	Yes
Option + Command + R	Rename
Option + Command + V	Extract Variable	Yes
Option + Command + Z	Analyze Stacktrace
Option + Command + Up Arrow	Extend Selection
Option + Command + Down Arrow	Shrink Selection

Note: some of these are the default bindings; some of them are not.
