Abstract
What are the effects of experience on text editing behavior? Do users inevitably develop optimal strategies for getting their work done? The answer to such questions are becoming increasingly important, as more and more individuals begin to use word processing equipment routinely. In the best of all possible worlds, experienced users do become experts, able to quickly and accurately choose and execute optimal procedures to accomplish any given goal. Such a state of affairs would make designers of editing systems very happy indeed. But another alternative exists, that at least some proportion of experienced and frequent users stabilize at some nonoptimal level of skill.
