I devoted a short chapter of my (now somewhat obsolete) book to this: Cocoa
Recipes for Mac OS X: The Vermont Recipes, from Peachpit Press. There is a
Cocoa API to implement enhanced tooltips when clicking on any UI element
while the question-mark cursor is showing. It's an old NeXT thing, largely
supplanted by built-in (Interface Builder) tooltips in Mac OS X. But you can
easily do some things with the question-mark cursor that you can't do with
tooltips, like show fancy fonts in your tooltips.
Nobody does this now. But the Vermont Recipes application you build with my
book (written for Jaguar) still works in Tiger. Run Vermont Recipes, hit the
Help key to bring up the question-mark cursor, and click a Vermont Recipes
UI element. Up pops a tooltip with italics and boldface text in whatever
font the developer (me) chose.
