Helps you type in four ways. First, it automatically corrects typing that violates conventional typesetting rules, such as typing more than one consecutive space. Second, it automatically corrects fast typing errors, words that are often misspelled, such as "teh" for "the" and "THe" for "The". Third, it can require modifiers to engage the Caps Lock and the Help key, making them more difficult to press inadvertently. Finally, in the event of a system crash, it can keep a log of what was typed. It supersedes version 3.3 and all earlier versions. Incompatibility with Mac OS 8.5.
