If I remember correctly (and this is going back several years), the Help key on most Mac keyboards is sort of hard wired to produce the question-mark cursor, and it was originally intended to invoke routines in, I think, NSHelpManager that allowed you to present super-tooltips. They looked just like the yellow tooltips we all know and love today, but you could add images and lots of other things to them. Nobody every used them in Mac OS X applications that I know of, but I devoted a whole chapter of "Mac OS X Recipes for Mac OS X -- The Vermont Recipes (first edition 2003) to how to do it. This facility is so little used that recent U.S. keyboards have renamed the Help key to something else. Oh yeah, there it is: "fn" on my latest extended keyboard, duplicating the function of the "fn" key on in the lower left corner of MacBook keyboards. I don't recall that there was any way to override what the Help key does, but I could be wrong. Maybe I even explained how to do it in the first edition of my book. -- Bill Cheeseman - [email protected] _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
