I get a lot of mileage out of Typinator, a Mac utility that automatically corrects typos or inserts symbols or phrases in your text. In addition to the built-in dictionaries, I have made my own additions that others might find useful, as well.
The first set is a bunch of common and not-so-common symbols. Rather than dig through the Character Palette to find a symbol every once in a while, I just type a little abbreviation. For example, when I type the abbreviation \star, Typinator automatically inserts “★” for me.

The second set fixes a few of my common typos. Combined with the built-in typo set, Typinator makes me look like a pretty good typist!
