Hi, I can not find how to check the help page of a function.
For example, I want to check the help page of "head". How should I do
it? (":help" doesn't seem to help.)

Peng

`:t head` will show the function signature (which in 90% of the cases
is more than enough to understand what the function does).
`:i function` will show the function signature and additionally tell
you in which module it is defined.
