One of the most venerable categories of utility software is that of the abbreviation expander. It's not surprising - computers are supposed to save us work, and who wants to type their entire snail mail address by hand every time when you could type "sm" and have a utility replace that with the full address? SmileOnMyMac recently acquired and updated Peter Maurer's highly regarded Textpander utility (and renamed it TextExpander), making it an excellent choice among these programs. Its expansions (which it calls "snippets") can include formatted text and graphics, are sensitive to the case of the abbreviation, and can themselves contain abbreviations that will be expanded too, thus providing nested snippets. It provides a menu in the menubar and another in the Services menu for entering snippets, repositions the cursor after expansion, and it can both export snippets and import them from competing utilities.
