Press W to open the online help. The help initially
provided is context-sensitive, that is, it is always about the
current view and its menu items.
For example, to get help on the Function app, press
I,
select Function, and press
W.
From within the help system, tapping displays a
hierarchical directory of all the help topics. You can
navigate through the directory to other help topics, or use
the search facility to quickly find a topic. You can find help
on any key, view, or command.
