Microsoft Windows 95 uses both vertical arrangements of items in lists and horizontal groupings of smaller vertical lists. This paper reports the results of an experiment to evaluate selection times using horizontal and vertical lists. Two GOMS (Goals, Operators, Methods, Selection rules) models were developed to predict differences. There was no significant difference in selection times, but the results showed interesting trends in learning behaviour.
