As for the Help business, for those who dare to see how much your
beloved TM's Help sucks, try this. Switch to the Finder, invoke Help,
in the search box enter anything you like, for example "preferences",
click on the first result, and now use Cmd-F to search for occurrences
of a particular word in that page. Pick a word you know is there.
Success! (So don't blame the OSX Help system for TM's developers'
incompetence.)
