The idea was to create the :ab feature from vim for X. You simply type some abbreviation, e.g. "mfg" and the program deletes "mfg" and writes "Mit freundlichen Grüßen" instead.
While the basic functionality works nice, it was not so easy to support any letters which cant be typed directly with the keyboard the user has. Even key presses with modifiers caused problems.
