Since OS X Leopard in 2007, the default Help menu in virtually all apps has contained a search box for tracking down the name of a menu feature you need. For example:
- type “new” in that search box in just about any app
- mouse or arrow down through the results
- the corresponding menu will open to show you where to find that option
It’s a really handy feature for finding your way around in new apps or tracking down that feature you know is there… somewhere.
For quite some time, many OS X apps have allowed you to hold keyboard shortcuts to modify some menu features. Try clicking the Apple menu and holding ⌥ (Option) for a quick example.
In Mountain Lion, searching in an app’s Help menu will now also highlight those hidden options. As in my example, there are three Preview features in this menu that you can enable by holding ⌥, and they each appear below their visible counterparts.
