Hitting the help key gives a ?-cursor, then clicking on any window,
button or whatever opens the help text (searching for the tool tip
string in the help book). So far so good.
But wouldn't it be nice if Apple could add (along with the tool tip
text) a help-url, and make helpRequested: open this url automatically?
Using the tool tip as search string is clearly only the second best
solution.
