I recently bought a new typewriter--one of those super-duper electronic marvels which does everything but slice bread. Among its many features is a built-in 50,000-word dictionary against which I can check the spelling of words, either as I type them or after and press the space bar, the machine will beep angrily at me and I will have two options: either I can press the space bar again, in which case the machine will reluctantly type the word as I spelled it (probably laughing quietly to itself at my idiocy), or I can ask the machine to search its dictionary and suggest words that I might have been trying to write.
