SpellText is a text-box component with as-you-type spell-checking and AutoType functionality. The spelling checker has a built-in dictionary of more than 135,000 words and an unlimited number of custom dictionaries, which allow you to add or remove any words you wish. Passive Checking flags any misspelled words as soon as you type them, and you right-click to get a pop-up menu of possible suggestions and other options. AutoType is a way for you to add short key phrases that are automatically replaced with longer custom phrases as soon as they are typed--perfect for standard headings, signatures, commonly used product names and so on.
Version 2.7 includes speed improvements and a couple of minor bug fixes.
