Zappy Macro
===========
DECRIPTION
A keyboard macro utility running as a loadable kernel module.
USAGE
The Scroll Lock key toggles recording of a macro on and off.
The key to the left of 1 (on my keyboard) replays the macro.
The Scroll Lock LED indicates that a macro is being recorded.
USAGE DEATILS
To avoid the playback button to generate undesired input, I
am using xmodmap to disable it like this:
xmodmap -e "keycode 49 ="
IMPLEMENTATION
Listens to the keyboard using a keyboard notifier and
playbacks macros using a virtual keyboard input device.
