Retention over time

How well can a user remember the interface after an hour/day/week/year?

Because I've tried so many interfaces and systems for this assignment, my head is swimming with telnet escape key combinations, WAIS server addresses, foreign language equivalents for Boolean searching, common gopher menus, etc. I have to look up almost everything at this point, or rediscover it when I can. The systems and tools most ingrained in my memory are the oldest ones-- command line utilities and the Dialog and Melvyl systems.

An example of an interface whose features are difficult to recall is Gopher. The user must be able to navigate a long series of complicated menus to reach the desired information source--something akin to jumping through a dozen hoops for a dog biscuit. If the average Gopher user is not aware of the bookmark feature (or cannot save bookmarks on a network), they must remember a long series of menus in order to find the same information during repeated use.
