This paper explores the behavior of experts choosing among various methods to accomplish tasks. Given the results showing that methods are not chosen solely on the basis of keystroke efficiency, we recommend a technique to help designers assess whether they should offer multiple methods for some tasks, and if they should, how to make them so that they are chosen appropriately.
