Abstract
We introduce GEKA, a graphically enhanced keyboard accelerator method that provides the advantages of a traditional command line interface within a GUI environment, thus avoiding the "Fitts-induced bottleneck" of pointer movement that is characteristic of most WIMP methods. Our design rationale and prototype development were derived from a small formative user study, which suggested that advanced users would like alternatives to WIMP methods in GUIs. The results of a controlled experiment show that GEKA performs well, is faster than menu selection, and is strongly preferred over all mouse-based WIMP methods.
