macosxhints - Use wildcards to build iPhoto smart albums:

This is an interesting little iPhoto feature I just found. When making a smart album, ? and * are wildcards. A ? will match "any single character," so that K??e will match "Kate" and "Kyle." A * will match "any number of characters," including none, so K*e will match "Kate" and "Kill me" and "Ke."

I couldn't, however, discover how to search for the actual ? and * characters. Backslashes -- the usual escape character -- don't seem to work; K?ate is treated the same as Kate, but K\ate will find only "Kate." Adding an 'escape' character (Control-Q, Esc) also failed.
