KeyRemap4MacBook is a keyboard remapper for Mac OS X.
Not to mention the change of simple key remap, it has the special remapping like Emacs-mode, SandS-mode (Space and Shift).
Very small & concise source code written with C++. Use it as codebase of your original keyremapper.

What’s new in this version:

Version 3.2:

• Added an existence check of DoubleCommand to installer. If DoubleCommand has already installed, the installation will be aborted.
• Support PowerBook G4 & iBook.
• Fixed the key repeat bug on VMware + emacsmode.
• Fixed a minor PreferencePane bug.
• Added new remappings.
