I've been instructed to implement tool tips for an app such that a
longer, more descriptive tool tip is displayed when the command key is
held down. Allegedly there was a way to do this in Carbon that was
part of the Help Manager API, but is there a Cocoa alternative? I've
had a look at the NSToolTipOwner protocol but I've been unable to find
anything that indicates it would solve my problem. I was thinking the
best way to do it might be to bind all my tool tips application-wide
to an object that overrides -valueForKey: which checks the command key
status, and returns the appropriate tool tip. Is there a better
solution?
